This thread is kinda weird— it seems to suggest that there is a OR here, but I don't see how any answer can be anything other than yes, both. Bitcoin is just another thing you can own, like coal or beanie babies— and it would be very unusual for it to be highly regulated itself at least according to the norms of the more free nations. ... but it interacts with the banking world, which is highly regulated. Some people will see it in their interest to try to work with regulators to achieve good outcomes for themselves (and everyone else), other people will go off in a multitude of directions which are not regulatory centric (and which, as a result, don't interact much with traditional banking). Both things will happen no matter what folks want overall. This doesn't bother me: The fact that Bitcoin is diverse is part of what makes it strong. Not only would "regulating bitcoin" (itself) be inconsistent with the expected freedoms in first world nations, it's not obviously viable so long as bitcoin is thoroughly decentralized.
The OP also brought up another question though... how do we fund useful developments which are highly decenteralized— and thus can't easily fund themselves— when they don't really mesh well with the banking/regulation universe that many of the big name business players that we'd hope to bankroll development?
I don't really have an answer— I think ultimately our inability to answer it might be our downfall. Eventually the people currently working on Bitcoin technology for the love and principle of it will wear out. Will we only be left with serious work being done by people deeply in bed with large regulatory-target businesses?
