I take part of my income in Bitcoin and spend it, both on-chain and Lightning Network, pretty frequently. I visit a number of local places that accept Bitcoin and use it for online purchases too. There are several Bitcoin ATMs in my city but they mostly have KYC with low limits and/or high fees.
For purchases like cars or real estate it seems like you'd have to be pretty lucky to find a seller unless you're not particular about what you're buying.
I've also started keeping more physical cash on-hand lately.
