On-Ramps: A Bottleneck or a Feature?

It seems to me that for all the talk of stablecoin payments and the inherent efficiencies, a significant portion of the real-world friction still stems from the on-ramps and off-ramps. We're effectively talking about bridging the crypto-native world with legacy finance, and the legacy side still calls the shots on KYC/AML, volume limits, and the general speed of capital ingress/egress. It's like trying to put a Formula 1 engine into a tractor – sure, the engine is fast, but the rest of the machinery is going to dictate the pace. Are we just accepting that these on/off-ramps will always be the slow part of the equation, or are there genuine innovations brewing beyond just more fiat-to-crypto exchanges? For instance, $GBPJPY moved up to 213.526 today, a standard forex move, but try to convert a significant chunk of a stablecoin portfolio to GBP and you're back in a 2-day wait for bank settlement, often with a hefty fee attached.

Am I just being cynical, or is the on-ramp/off-ramp issue fundamentally limiting broader adoption for merchants and fintechs in a way that simply more stablecoin options won't fix? Push back if you disagree.
