This question has been ask here for a long period of time and the answer will always be "NO", Bitcoin cant be regulated by anyone nor a powerful government cant.
Bitcoin doesnt have a main server to begin with thats why it cant be regulated.
Bitcoin will be regulated, and can be regulated. It is open source, that means your government or
anyone can track you. Even now you have some kind of regulations, US citizens can not deposit money
in all exchanges, or gambling sites. They can do it off the record but if they get caught they can be
punished for that.
How I see it government can ask you to make official wallet with your ID and if you use bitcoins for
something illegal they will track you easily. If you have some secrete wallet if they connect that wallet
with you you can be punished for that.
There are many regulations, I think some of them can be applied on bitcoin too. Like you said no one
will be able to control supply of bitcoins, but usage can be controlled.
