How are there not real use cases for crypto already?

Surely more business is being done with crypto today than was done using the internet in the 80's.

I've been paid my salary in crypto for the last 8 years. The company I work for pays nearly all their expenses in crypto. I pay for my rent and most major purchases with crypto. A significant portion of my savings is in crypto. For fiat purchases, I'll use a reloadable crypto visa card. When I travel to foreign countries that mostly use cash, I'll usually exchange crypto for local currency rather than carry large amounts of USD or deal with sketchy ATMs.
