> Yet just about everyone uses local FS with cloud for backup or sharing of a small subset.

In most cases, not because they want to, but because that's how current software works. Both Dropbox and Google Drive focus on having their own special folder that gets synced; syncing the OS desktop and documents folders is possible but only with special configuration (on both Windows and macOS).

Cloud first makes perfect sense no matter how much or how little storage you have. It prevents you from losing data if your device is lost or damaged, and if you have multiple devices it allows accessing all your data from any device. If anything, its usefulness depends more on internet connection speed.

I do think Apple's specific cloud storage offerings could be improved for large devices. Currently the highest tier of iCloud storage is 2TB, which costs $20/mo; that's only twice as large as my MacBook Pro's SSD, and fairly expensive. But it's the same price/GB as both Google Drive and Dropbox, so it can't be that much of a ripoff...
