What if Real Life worked by RAW?

If you're the one building the computer and crafting the plane, it's not too bad. You don't have to pay anyone for spellcasting. And if you're naturally talented enough to reach a level where you can create your own demiplane, you can regain any XP you spent on it without too much difficulty.

Still, it wouldn't be like the modern PC, where just about everyone and their dog can afford one.
