I think it’s canon that wether in DnD or PF anyone can learn arcane magic if they take the time to do so (and they have a way to pay for it, most people can’t afford to not work for 5-10 years)
The thing is, even if someone has the money and the time maybe they don’t want to spend it, especially if magical scrolls/wands can let you cast spells fairly easily.
To me it’s the same thing as saying to some kid “you can learn to be a robotics engineer and in 5-10 years and $100k of debt you’ll be able to make robots that can do anything for you, including being strong” and the kid just replies “That’s cool, but I think I’ll just go to the gym thank you”
Anything kernel level can theoretically modify anything in your TPM too, so Linux programs that use it (admittedly I’m not sure any user program use it) could be manipulated in weird ways
