The anonymous structure of the blockchain technology is a breeding ground for criminal activities life money laundering, drug trafficking?
No, pseudo anonymity of Bitcoin does not encourage criminal activities. The fact that we are dealing with something that has value, gives it more incentive to be used for crime. Do not forget that Cash is more anonymous than Bitcoin. Criminals do not have to be encouraged to use anything of value for crime, they just do.
Bitcoin transactions are traceable on the Blockchain, under certain conditions, which makes using this for criminal activities a very stupid idea.

I think this is delusional. Anyone with a brain that's about to commit crime would use a mixer to hide their tracks. I tested a mixer out of curiosity once with some BTC, and it really makes it a mess to track the coins back. Unfortunately I can forget about cashing out these coins now to buy some property because I will not be able to justify its origins after the inputs became all a mixed mess, and I don't want to be labelled a criminal.
It is what it is, despicable criminals will profit from Bitcoin, just like how good people that need to move or hide wealth from totalitarian governments and other attackers will profit from it. It's a double edged sword, but then again what weapon isn't.
