That's not true at all. It can be regulated without being controlled. The SEC regulates all companies that sell their securities to the public, but the SEC doesn't control any of them. That's just one example of how regulation doesn't necessitate control. As it relates to Bitcoin, there is already regulation. New York has the Bitlicense for any company dealing in crypto in the state of New York, and it doesn't require any control over Bitcoin or blockchain at all. The fact that it was happening already and you seemingly didn't know about it shows how regulation and control of Bitcoin aren't related at all.
I think there is a subtle difference between regulation and control. I agree with you that the SEC doesn't control the companies which issue securities and sell them to the public. But the SEC controls the market where these securities are being sold. In this manner, regulation comes about as a desirable and intended side effect of control over something else. On a more practical note though, if this commission changed their attitude toward stricter regulations, that would make lives of these companies heavier, up to a point where they would be cut off from the money of the crowd. Thus, while regulation doesn't mean control, it still weighs a lot in a practical sense.
