afaict, the main advantages of buying things with crypto are (potentially) lower transaction fees and latencies, and less red tape restricting who can buy what from whom. If you use a "tradfi onramp", doesn't it negate all of that? Why not just use tradfi all the way, for that transaction?

[mothballed]

There is no requirement to use the tradfi ramps. It is merely offered as an option. But as it pertains to banking in the USA, a couple differentiating qualities I will offer before the goalposts will inevitably be shifted yet again to damn my response

1) Settlement time (wires only sporadically free in US, plus usually settle slower)

2) Irreversibility.

3) The tradfi ramps, if used, only have to be OK with crypto ramp, rather than the whole host of underlying transactions. It is conceivable some banks will tolerate crypto while not tolerating, say, directly handling a particular transaction.

4) Lowered friction for international transaction

5) One or both sides can be unbanked.

Even if you're willing to operate fully in the "tradfi" system, your counterparty might not be, and you still want their business.

Citation needed. I'm looking at the transaction fees for lightning network and they are in the range of FedNow or RTP.

For Bitcoin it's not even close.
