Roadblocks, both in the U.S. and in other countries where it should ideally be less of a hassle to use.
Bills, groceries, generally fun experiences should be able to be paid for with Bitcoin if it's not an unreasonable ask to implement. Even with something like Bitwage existing, employers should be offering ways to earn an income on Bitcoin natively rather than through a fiat passthrough like Bitwage.
I'm not ungrateful for it existing of course, but I just wish more could be done with Bitcoin without gimping yourself in the process. Every day I get reminders of how difficult life can be if I don't even have fiat cash, and I'm pushed to just get a prepaid card so family and the rest of the world that refuses to catch up can just fuck off.
