You are confusing freedom with getting away from accountability. Tor being monitored by law enforcement is a very good thing in general. That simply enables them to do their job. Therefore for civilized countries it's definitely helpful.
Unfortunately not everywhere law enforcement is doing just that, catching criminals that is. In many countries they are used to maintain questionably legitimate governments and their established regimes. In those cases Tor and VPN services are the tools of freedom and their lack of transparency helps to spread information that otherwise would've been blocked.
Now think about it, do you as a citizen of a free country think that a) pedofiles, hitmen, large drugs distributors and all credit card thieves should be totally safe doing their business right under noses of law enforcement who you're paying your taxpayer's money while they can't do shit with that encrypted traffic; or b) provide an unreliable communication channel to the rebels or oppressed opposition of some other countries while their government would in the end just block everything by default (hint: China)?
The thing is, HTTPS and VPN are mainly used to protect your privacy and they have been working really well. While Tor is mainly used to avoid accountability.
