(1) If the user can't install the regular tor package that means that
someone else has enough control over his system that he can't trust
any validation on his system. Short of abusing the treacherous
computing for good, there is no real way to have confidence in any
validation system running on an untrusted machine.

More practically important,

(2) If the user can install the torbutton software he either could
install tor directly or a version of torbutton can be shipped
_including_ tor itself.


(3) If the server in question provides the torbutton it could easily
provide a modified copy of it. So this doesn't eliminate the
bootstrapping problem.
