It might not. I have a Raspberry Pi 2 that has been running a weather station for over 12 years, and it has been on the original SD card. I have other RPi's doing dumb things around the house and I have never had an SD card failure.
YMMV and all that.

Yeah, I haven't had issues with SD cards in a long time. Many years ago (maybe 10), I think they weren't quite as good and I probably skimped too much when buying a card. RPi 1 also had power regulation issues. Now I only use higher tier cards and make sure there's enough free space for wear leveling and operations.
HA in particular creates a lot of log churn. It's not a 100% certainty, but after running for 4 years I finally had to copy the SD image to a new one because it had become unwritable.
My friend bought an ODROID and an SD card at the recommendation of some tech YouTuber for Home Assistant. Within 3 years the SD card was dead, and I had to help him re-set-up all of his stuff (this time, with a more resilient storage medium and remote backups).
YMMV certainly applies but I feel like the warning is important.
I wouldn't put running a weather station in the same class of disk activity as running Home Assistant. It is writing a fairly large amount of logs, plus statistics for every attribute/sensor for every device. The more devices you have, the more you will be writing.
There are regularly threads from people with "I restarted HA and now I get this weird boot error message", and it's because their SD card died.
You do you, but it's common enough of a problem that I think it's worth calling out as a "Don't do this".
Dirty power kills my raspis faster then write cycles. I've been really surprised with the stability once I moved by Pis to my UPS
