I don't know on what planet do you live on where everyone around you accepts BTC directly, but please come to Europe and try living your life where 99% of merchants and landlords want Euros in exchange of goods & services.
I live in europe. I live only using BTC.
You do not have to onboard everybody.... just few basic merchants and you are done.
I have 2 local shops that are begging me to order anything from them, only to pay with sats.
