Fast fashion isn’t even considered clothing for some peaple. XD Just put your jeans, your t-shirt and your sneakers and go to work, the modern slave outfit.
Your smartphone is already an always connected device, and you can manually do periodical backups on external drives which is a good practice in any case.
You can also set which device rules the file modification (sent or receive only as a folder).
I think it’s ok for most of the people. If you have a tons of precious files to save I can agree with you, but I think this type of “off-grid self-hosting” is just the future of personal data management.
