Wouldn’t you just use AFS, CEPH, NFS, or 9p?
I really don’t want to be that guy, but isn’t SSHFS (FUSE) actually a terrible option when compared to an actual file-system? MacOS isn’t really missing out on much there.
The most painful part of MacOS (which makes it downright unbearable for me) is that system configuration files are XML. It’s an absolute nightmare.
I would like to avoid going on a rant, so I’ll just say this - capitalism does not work. The phenomena you are describing (… now people have too low standards) is called “tyranny of the majority” and capitalism does not have an answer for this. Hence why we really need to figure something out.
As a side note, I do not think communism nor socialism are the answer either! Despite what many are led to believe, we live in primitive times and have not figured out a sustainable economic model.
