Spend & replace is the way. Medium of Exchange only works if we use it!

Yep. Don't need to touch main stack, but having a wallet just used for spending, or using a couple fiat sites to pay a bitcoin invoice. I think Cashapp and Strike you can just have fiat there but pay lightning invoices. Allows more bitcoin to enter the circular economy.
I like to use Strike. Not only is Jack Mallers a great leader, buying sats in realtime to pay via lightning means no akward capital gains questions to deal with at tax time.
I have Cash App, but I don't use it. Strike - this is where I DCA.
