yeah, this is exactly true.

there are few usecases where monero is better than cash, and that's mostly only if you're participating in an economy that uses monero (and i don't know of any). everyone with monero wants to get cash for it so they can buy real things

and to buy monero "privately" with cash, you still need to go through literally every step you have to go through for physical money

and like victoria said, the use cases for monero are Mostly Very Illicit Goods anyways
