I own this painting:

I call it: dollar quoth over its base laying lover. As in the BTC/USD pair.

I'm of the counterintuitive belief that fiat (esp USD) developing a more intimate and frictionless relationship with bitcoin is a very good thing for bitcoin. It seems for many reasons the LN is the best tool for that, and calling them stablecoins when they're technically indistinguishable from bitcoin fails to consider the important nuance and differences between these and other L1s where they exist as separate tokens. To get from A-Z with bitcoin becoming the unit of account, etc, there are quite a few letters to pass first. I've thought about the game theory of stablecoins quite a bit over the years, and reject the idea that bitcoin being an antagonistic discrete payment network is the fastest way to achieve what you talked about.
