>doesn't that mean anyone can learn any spell as long as you have enough time and money?

It has to be in your class and is limited by your level.

>Wouldn't that make nobles basically invincible?

You are allowed to learn any spell in your class and level when you level up, usually 2, some classes like Clerics get all of them immediately.

>Also cantrips are supposed to be spells you have internalized so well that you can basically cast them in your sleep, not something you learn in a day for 25gp.

Now you can, you're welcome. Cantrips are arbitrary with your custom classes. I'm just providing you a lore friendly way to respec.
