If bitcoin is regulated like fiat, it will be as bad as fiat money and no one will use it.
That's the beauty of a decentralized currency built on a P2P network - it can't be regulated (unless interference with the internet counts as regulation). But as long as we have a need to convert between fiat and bitcoin, then governments can attempt to regulate the companies performing these services.
In this case, I think WU is full of it. We don't need WU to transfer bitcoin and they know it, regulation is just a straw man.
A decentralized currency like bitcoin can very much be regulated. It would need to be regulated when it is traded for fiat
