not really. You're assuming that you, as a remote user, trust root. That's
not a good assumption in a distributed computing environment. Someone you
don't know can become root, root can become anyone, then become you, then
the permissions are a moot point.
You're also assuming that the owner of the system is willing to let you
"own" a file in the local file system. They may let you be willing to use
their cycles, in trade for some of your cycles, but they may be a lot less
willing to let you see their filesystems.
These are both faulty assumptions in distributed computing environments.
People have killed distributed computing in some organizations for these
reasons.
