Because storage is cheap for everyone except Apple, that knows they can get 60%+ markup for everything they sell.
meh, Apple's certainly not alone in their profit margins on upgrades. It's a fairly universal strategy to keep the baseline appealingly low. Dell, for instance, charges $400 to upgrade from 16GB to 32GB RAM on some racks.

Apple's memory upgrades somehow still manage to be significantly more expensive than the significantly overpriced Dell upgrades.
But that just depends on use-case.
There are plenty of scenarios where you just need the built-in storage to handle the OS, apps and miscellaneous storage while your large scale storage is external somewhere.
Why make people get (and pay for) more storage than they have use for?
