Gary Gensler actually said...

The reforms mandated by Congress will reduce systemic risk to our financial system and bring sunshine and competition to the swaps markets.

part of that cost is so that the taxpayers do not have to bear as great a risk to bail out financial institutions in the future.

Congress said that those transactions that are cleared and made available for trading would be brought to swap execution facilities.

I think that markets work best when they are transparent, open, and competitive.
