Before I get into things, I would like to thank whoever threadmarked my Alchemical stuff. Thank you! I put a lot of work into these, so that's really flattering!
Or is it the notion that one has to have some special trait to access certain kinds of magic that makes it a problem, so the problem originates with the combined notion that a Thaumaturge/a Sorcerer are a one in a million kind of person?
This is a big chunk of it, to me anyway, because for the longest time Thaumaturgy has been "everyman magic," to the point that in 1e it was called Mortal Sorcery instead (terminology confusion be-damned). The highest feats were undoubtedly the domains of savant-scholars and the highly educated elites with decades of experience and resources to draw from, but it was a given that any given footslogging soldier conducting the correct practices to Mars for safety and power in battle, or that threshold nomads appealing to the spirit of a given animal for a plentiful hunting season, actually
understood what they were doing and not making meaningless and hollow gestures out of ignorance.
Because we already
have Special People Magics, in the form of Sorcery, Godblooded gifts and spirit-blessings, Celestial and higher martial arts styles, legendary and unique artifacts, and finally the Exalted themselves. By decreeing that any/all forms of magic are so far outside the mortal frame of reference it is not even Possible to perform anything other than baseless superstition and ritual as total frauds, even if unaware of their fraudulent abilities, without some form of Golden Ticket to plot-relevance means that the setting is
less magical and becomes seen as less magical.
By promoting the view that "ignorance is the norm, true magic is rare and mysterious" players left to such a setting will
not go looking for mundane people to provide their solutions, or embrace the exotic elements of the everyday world outside of the clearly denoted "these things are Always genuine fucking magic." Because the odds of that search leading to another snake oil salesman or astrologer pulling blind horoscopes based on context cues of your dress and demeanor are suddenly much higher when any logical course of action says "lets go find the nearest Exalt or god, they're the only people who really matter here."
I like to go on about Autochthonia primarily because it is an
entire setting built upon the premise that mortals no longer have to compete with an abundance of Special People constantly overthrowing whatever safe status quo they can maintain, and as a result they have managed to successfully build entire institutions atop the systematic rules created by the natural magic of how the Great Maker operates. Consistant, repeatable magic able to be applied by even the lowliest menial lever-puller is how their society has managed to persist in one of the most harsh and inhospitable environments imaginable for almost 5000 years. That understanding is how they have built their technology, their culture, their laws and religion.
Stability and practical knowledge are why Thaumatugic Arts in Autochthonia are deliberately called
the Sciences.
