Yes this is the main reason for me. If you’re alone then you don’t care that things occasionally don’t work. Once you have at least one more person or potentially the extended family it’s a whole different story. And then in my opinion a potentially not 100% secured publicly accessible immich instance at home is magnitudes better than having the family just use google photos.
Because like you say, every little hick up from your site is met with “why can’t we just use $bigtech instead, it always works”.
I think you will need to have a mix, not everything is S3 compatible.
But I also like S3 quite a lot.
