There are still many barriers to that "first class" status, taxes are mentioned most often.

Taxes are paid in fiat. Holding non-stablecoins would add even more of a tax headache because you'd have to track capital gain/loss as you enter/exit fiat for taxes / fees / vendors that don't accept crypto

Also the fact that general adoption has been slow so far may be a sign that there is not enough obvious value added for the average person to consider using crypto over fiat.

who would pay with non-stablecoins though? The oath seems to be cbdcs that are compatible with public smart contract blockchains

There's also the risk that stablecoins aren't actually stable but just claim to be such: https://www.coindesk.com/tether-first-reserve-composition-re...
