Yea, the physical key is, to me at least, one of the top human inventions.

Ubiquitous, cheap, convenient, and provides sufficient security. My little brass key never needs charging, never refuses to open the door because I didn't apply the latest over-the-air update, doesn't phone home to an advertising firm to track every time I open and close a door.

I can make as many copies as I like and give them to friends and family in case I lose mine. There are some scenarios where it might be nice to have a smart lock, but for me at least, they are so few and far between that I'll stick with this tiny bit of metal.

I completely agree. I also call "citation needed" on physical keys being replaced.
