Why on earth are you so opposed to the idea that if we try to steal, and we get caught, bad things might happen? How is this so utterly implausible to you?
I'm not, and haven't been - nor do I treat it so in any regard.
I am wholly aware that we could get called out, that our attempts to cover up could fail, that we could be outed and all that.
Instead, I'm simply highlighting that
relative to all the other possible risks of discover about the Gamer status, it's one of the easiest to do a patch job coverup, one of the easiest to explain away due to it's nature, and as such, isn't worth all that much attention
compared to all those other potential risks.
Like say, I don't know... picking up DnD associated Gamer skills involving magic, or levelling Fire resistance and pain resistance to the point he can tank things like a proper game character, or any of a myriad of other things.
What means? Throwing us off a balcony to see if we bounce? Checking to see if our wand has been used? Wizardign techniques for detecting wizards aren't really an exact science.
So how do the school letters find people, particularly muggleborn, so reliably - because if that's not built on an 'are you a witch/wizard' detection system, then I don't know what to say.
And if they have some sort of Wizard/Witch detection system they can tie to a school enrollment system, then I doubt they can't independently apply that detection system.
And if that detection system, as seems rather likely, notes Dudley as 'not a Wizard', well... that sure could be useful at obfuscating things, even if it might not necessarily be some sort of perfect secret protecting thing.
I think this option has somewhat more risk than most options. Most options that we have in this game are essentially risk-free.
Dudley learning most
anything from the 'go steal, pillage and kill and you'll be rewarded' mentality and skillset of DnD is far, far worse than anything theft related.
He's at an influencable age, he doesn't have much common sense, and seeing what the book says 'proven' by how he can actually do it is a very worrying recipe, for his ideological and moral development. He did invent Harry chasing well before now, so we know he's not exactly a fundamentally 'good' kid at his current age. Heck, he has no problem learning about stealing, what with how the vote options were presented.
'I got in trouble for stealing something' is way, way less of an issue than 'I got caught setting people on fire', even if it's less likely - just like the low chance of murder is generally treated as a bigger issue than a medium to high chance of getting violently (but nonfatally) mugged.
This one is not. It's using our power in an obviously strange way, in a place where we could be seen, in a manner that is fundamentally hostile to at least some of the people who could see us (and also one that's illegal). I think it's a reasonably amount of risk, and, with some care, can be managed. I think it's probably worth it. At the same time, it's still higher-risk than, say, practicing boxing a few more times, or getting involved in D&D, or doing our homework. I think we should do it, but I think we should be aware of the risks going in,
I'd be entirely on board with this claim if you hadn't cited DnD - all those other things are, indeed, far safer.
Buuuuut the way you lumped in what sure looks like
the most dangerous option makes me unable to agree.
