You sure have a lot of posts on a Bitcoin forum for somebody who thinks only stupid people use it!
If I'm understanding your post correctly, you seem to be assuming that bitcoin will only succeed if it can be used by criminal enterprise, which just seems to be untrue. Yes, a lot of us expected the BTC/USD price to fall dramatically following the Silk Road bust (and it did, for a pretty short time, and not that "dramatically"), but as that phenomenon showed, there was no lasting impact on the actual Bitcoin exchange rate once it initially recovered ~24 hours later.
Secondly, the traceability of bitcoin isn't an issue, because nobody (even criminals) cares that their transaction history is completely public as long as they make an effort to keep it separate from their identity (i.e. not using it alongside one's real name). If you want to make a completely anonymous bitcoin transaction, it's extremely easy to do so with some very minor precautions.
As for registering your wallet to an IP address, how do you think the government would enforce this? Which government would put these restrictions in place, and on what authority?
EDIT: I think I misunderstood your title. For anyone else's benefit: I don't think Interized is saying Bitcoin is used solely by "stupid criminals", he's saying that the only criminals who would use bitcoin would have to be stupid. I don't think that's true either, by the way. Am I right, Interized?
