However it is also a fact that most (but not all) of the folks behind the myriad of altcoins DO NOT think that they have ANY fiduciary responsibilities and as such act only in their self-interest (can you say shitcoin pump-n-dump schemes?). It is because of those crypto coin developers acting irresponsibly and all too often, fraudulently, that she has concerns which may need to be addressed through legislation.
But what it would mean in reality? That developers must comply with regulations before releasing open-source software? I don't see how this can be enforced, especially since crypto is a global phenomenon that ignores borders. Best they can do is to tell exchanges which coins to list, but we're already in era of decentralized exchanges, so even that won't prevent people from investng in scamcoins.
