Which anyone can do when combining CC-By and CC-By-SA works by others.

don't use CC-By)

Which only the copyright holder(s) of the BY-SA work can do.

Not so, see above. I can't combine the NC-SA and SA works of third
parties without negotiating alternative license terms; the licenses
are mutually incompatible.

The limitation of BY-SA keeps the work and it's derivatives freely
licensed. True— it's a limitation, but it's one that merely
contravenes some of frequently anti-cooperative aspect of copyright
protection.

You can look at SA works as existing in a parallel copyright universe
where restrictive copyright controls do not exist. This is
categorically different from the (often vague) nature of use
restrictions connected with non-commercial licensing.
