True but that’s not necessarily a given and won’t be an immediate concern.
I ran my first install on a RPt3 for almost a year on the same SD card without issue before I moved to the NUC. That card was still fine even then.
And if you want to mitigate that then run it on a RPi3 from an SSD (I only say RPi3 because I haven’t heard definitely if the RPi4 can be run from an SSD).
Either way running HA from a image on a Pi is still way easier. It’s not necessarily better (for reasons we won’t get into here) but it’s definitely easier to get up and running smoothly without needing to jump thru the potential hoops needed to run everything in a VM.
