It's hard to picture a 'legal' use for something that is tied to a proprietary API.
Also, TOR was funded with illegal uses in mind. Beneficial to the US government, perhaps even legal with the US, but illegal in their intended application.
In what way is browsing the internet without someone recording your every move illegal? You may choose to use the anonymity for illegal purposes. But you may also choose to use your car or house for illegal purposes and no one says that these should be illegal.
Tor was, in part, made for countries where that is illegal.
As for bans on knives and such, I consider such bans just as unjustified.
