I've easily transacted on chain thousands of times and I still use self custody Bitcoin daily. But honestly, I've probably made less than a dozen on chain transactions this year and most of those were to open or close lightning channels. I buy and withdraw to lightning, save in liquid when channels get full and only move to cold storage when I have a decent UTXO saved up. I don't NEED on chain Bitcoin very often anymore.

It worked. We scaled Bitcoin.
