You're actually talking about the same problem. Competition in healthcare is heavily restricted by stuff like certificates of need because there is little cost-sharing with utilizers so you get overutilization & induced demand. This is Roemer's law [0]. A large part of the reason for competition restrictions is because of a hacky attempt to control overutilization without direct cost-sharing.
