It’s not reasonable because you’re assuming that 1) they have the time to set up that network infrastructure 2) their skills align with that 3) they have the knowledge to do so 4) they live in a country without strong regulations that would make such a thing unnecessary.

Just because you know objective-c doesn’t mean you know a damn thing about raspberry pis, backup programs, NASes, or anything else. It doesn’t mean you know or want to manage your own network infrastructure. They’re a Mac app programmer, not a Linux professional, not a micro-computer professional, not a network engineer, not a sys admin.

Time Machine wouldn’t work here, because it needs the files locally and he’s already stated he doesn’t have a 6tb drive.

1. I am pretty sure OP could manage to plug in an ethernet cable. 2. Again, he should be able to manage to set up a computer and plug in a USB drive, even if not familiar with the particular OS. People are not that narrow 3. I am pretty sure he could manage to install and run some backup software on his devices 4. I assuming you are missing a not there, but regulations have clearly not solved the problem, in fact its likely AML regulations caused it.

Someone who uses a $500 gift card to renew subscriptions could afford one

So that solves it for OP, but not for every single other person out there who's not as tech proficient and relies on iCloud for backups.

Which is not an unreasonable thing at all considering it's literally marketed as a storage solution for your photos, and a top of that even encourages users to store originals only in the cloud.

It won't solve for people that only own an iOS device but setting up a Time Machine backup is aggressively recommended by OS level notifications for every macOS users.

A simple usb hard drive will actually do, no need for a NAS. The only action required to implement proposed solution is to check "Keep all data on this Mac" in both photos and iCloud Drive settings. And to be extra cautious add a second backup drive from another vendor (to be extra extra cautious don't use Time Machine for the second drive).

For the specific case of thoses that don't have a big enough internal drive they might need to store data on an external drive. But if you do have 6TB of pictures you normally should ask yourself if a RAID1 or RAID6 is not warranted at this stage.

In conclusion it's not a binary decision there is lot of room between "I solely rely on the cloud" and "never trust the cloud".
