That's your opinion, not a fact. Car manufacturers are required to put seatbelts in their cars because of regulation. In this case, it's not done to "decrease competition". It's not done to "increase monopoly". It's not done to "create central hubs of systemic risk". It's done to save lives. Regulations affect profits, yes. Regulations may have unintended consequences. Making regulations that protect people and still allow for a healthy free market is a hard thing to do. It's heavily context- and market-dependent. It is what it is and we have to live with it, but it's not as black-or-white as you make it sound.
