To the extent that regulatory capture is itself an inevitable outcome of capitalism, maybe.
That is mostly tongue in cheek of course, but it does really bring up a point in that if there were stringent controls on regulation it could help minimize the issue. And if nothing else there's some beautiful irony in regulation being in need of regulation.
It would just shift attention to the organs of government controlling said regulation. The insight of democracy is it seeks to balance, not suppress, human nature. Capitalism and democracy healthily co-exist because the former produces the private property rights that keep state power in check. Keeping that checking function itself balanced is the crisis–and opportunity–of our modern era.
