Free market means people can choose whatever shitcoin they want to do business with, so long as the seller will accept that form of payment.

This is a shitty argument: monero is the free-ist coin so you really have no choice but to use it because it’s already used the most and is the free-ist. If you choose something else that’s not the free-ist of free markets bro. You have to choose my coin to be free.
