On-ramps for merchants: Still more trouble than they're worth?

Been following the discussion on stablecoin payments for merchants, and I'm still not convinced the juice is worth the squeeze for most. Setting aside the actual transaction fees, which can be competitive, the backend operational lift for smaller to mid-sized businesses just seems immense. We're talking about managing treasury in multiple currencies, navigating potential tax complexities that vary wildly by jurisdiction, and then the whole UX hurdle for customers who aren't crypto-native. I get the vision of seamless global payments, and the idea of bypassing traditional banking rails is appealing, but for a local shop, or even a regional e-commerce player, are the promised benefits truly outweighing the headaches of implementation and reconciliation? It feels like we're still a long way from mass adoption, despite all the bridges and on/off-ramps being built. Case in point, even with $AUD holding steady around $0.0936 (after a day that saw it bounce between $0.0911 and $0.1028), the volatility against stablecoins for some merchants is a non-starter. Convince me I'm wrong.
