Let's flip that around. Do you think it's good for the game that I can tell a king to strip naked, eat his own shit and strangle his wife to death in his own throne room with 1 success normal social combat hits? Because I can, by RAW, once I burn out all his WP by commanding him to rip out his own eyes and swallow them, behead his loyal councilors and spend all his money buying elephants, all of which he will, naturally, resist doing because doing so would be completely unacceptable. Should the rules allow this to happen? Does that make sense? Is this a reasonable expected outcome?
I'm going to assume that as a reasonable person, you'll say "of course not, that shouldn't be happening, the system is clearly bugged if it allows you to do that". What allows me to do this? The ability to compel actions unbound by any restrictions except I can't order a suicide or going against the person's Motivation, with no limits except I can't give the same unreasonable command more than twice in a row if the target still has WP to spend desperately blocking. Is this actually needed for anything? What bad stuff happens if I delete it? Why... nothing! Nothing breaks, because this isn't something you expect a normal conversation to be capable of in the first place. Well then, what should we do?

Okay, what's left that we can do with social combat 1 success hits after we've deleted this outrageous thing? Nudge Intimacies up or down. Find stuff out. If I want to make people do anything with this, the best I can do is to crank up an Intimacy until they get around to doing it themselves, which is more or less how normal persuasion works in real life. Looks pretty good now, right? Does Solar Bob have an overpoweringly strong incentive to behead anyone who can beat his MDV after the first Presence roll now? Do NPCs have an overpoweringly strong incentive to try to kill Solar Bob the moment he starts hitting them through their MDV? Nope, not anymore.
Telling the king to rip out his own eyes falls under the general "self-destruction is an unacceptable order" rule - as it happens, errata on the effects of Abyssal iconic animas actually mentioned eye-ripping specifically.
Beheading loyal counselors might normally involve more than one successful social attack. Usual logic would start by eroding the relationship, then persuading the king that having them killed is necessary, and then probably bypassing whatever judicial checks and balances would normally be involved is a whole separate issue. But... no, that's not strictly necessary.
Iago rolls enough successes on "strangle your wife" while she's right there in arm's reach? Othello's got a short list of bad options: spend WP to resist, or commence strangling. If Desdemona wins Join Battle and jumps out a window, though, the subsequent chase is a new scene - meaning opportunity to reconsider without even needing to spend any WP. Most likely outcome at that point is Iago, at minimum, losing 'trusted lieutenant' status.
Incidentally, virtue compulsion has a hidden advantage here: when someone's completely out of willpower, they cannot act against any virtue rated 3+ unless it was already suppressed... so social attacks opposing such virtues become
impossible orders, resisted automatically at no cost. Murdering a faithful ally in cold blood clearly goes against Compassion AND Conviction, plus Temperance if doing so would violate an oath (e.g. marriage vows), so that's not a line anyone with a heroic virtue spread needs to worry about being shoved across just because they're having a bad day. Unless they took max Valor and nothing else, of course, but there's not so much room to complain if they clearly signed up to be violently unstable right from the start.
If you can overcome the king's MDVs, complete with relative-magnitude bonuses from the court full of witnesses, Defend Other from those loyal counselors, and various intimacies or virtues which would oppose such a senseless action? In-character, you've somehow built a very solid case
[REPOST] Epistemic Learned Helplessness for why he should publicly humiliate himself, an argument that it'd cost him something (willpower or loyalty) to arbitrarily reject. He might decide not to pay, or not have it to spare, and just go along with the bad idea. If so, congratulations, you've egregiously embarrassed someone powerful enough to deploy armies or assassins over a personal grudge, and thus given them more than merely personal reasons to do so. Now what?

The point of a longer con, from an optimization perspective, is to avoid committing to anything so overtly hostile: once someone notices your arguments leading them in obviously bad directions, they'll stop giving you the chance to talk at all. Challenges of getting your (figurative) foot in the door is where the longer-timescale Bureaucracy
Atomic Robo - v12ch4 - page 15 and Socialize
Atomic Robo - v3ch4 Page 1 system would come in, if it were in functional condition - and no, it isn't anywhere near ready yet. Second edition, start to finish, was essentially an incomplete draft, still waiting on several rounds of expansion and revision by editors and playtesters. There's no stratum of mature chicken you can reveal by carving away 'nonfunctional' pieces of an unhatched egg. I'm not saying it's unbreakable, or that the immediate problems you point out aren't real, I'm only claiming there's unfulfilled potential to be built on.
As for buying too many elephants... man, if you think it shouldn't even be
categorically possible to directly bamboozle people into making
suboptimal financial decisions, what the hell are social stats supposed to be good for? The main way a king avoids spending everything at once is by not carrying around the entire treasury in cash. Here, Slately asks for too much money:
Book 2 - Text Updates 042 and after some back-and-forth within that single scene, Don King agrees, but
lacks the ability to immediately comply - setting aside irrelevant details of the magic system, he effectively needs to spend another scene (lower half of the very next page) talking to somebody else, with the original petitioner out of earshot, in order to unlock the vault and release the funds. That kind of psychological benefit from procedural delay is exactly why stable institutions have checks and balances, and gun laws have waiting periods: to limit the damage possible due to a single-scene lapse in judgement.
Inherent perils of absolute power wielded with imperfect judgement is a core theme, and being able to talk someone into making
incredibly awful short-term decisions (with a lucky roll, when they're already having a bad day and thus don't have the willpower to spare) reinforces that theme.
