Say that there's an "effective" ways to block Tor. What's to stop people to just abandon ship and use yet another anonymizer? Tor isn't the only one in the game, there are others. Then they'll be calling to block those as well, and people just pick up yet another one. This will go on and on until everything is blocked including legal channels.
The only sure way to stop crimes/abuse/cyber-blah is NOT having internet in the 1st place. Are anybody willing to make the commitment to obliterate the internet entirely "just for the children"?
I'd say enough is enough. Choose: either have unfettered internet or destroy it entirely. We can't have it both ways, and anyone saying there's a middle ground in this is delusional at best.
-- though it seems as if amateur blogs and the like often seem a lot faster about making corrections...
Well, to be fair, "amateurs" tend to be less multitasking, hence can keep a significant focus on the topic at hand. Hence errors can be more readily detected and rectified.
Pros, however, tend to multitask a lot, and focus are divided among several topics, and not to mention the "check and balances" guideline they must adhere, which tends to be much more stricter than those adhered by amateurs (cos their names depend on it). Errors are slower to detect, and once detected, there's the check-and-recheck phase. So, in terms of error detection and correction, "amateurs" tend to be more "agile" and "robust".
Of course this is an over generalization and simplification...
