> They are often the result of companies bribing or otherwise coopting the government to enact those regulations.
Which is the thing that does this:
> automatically discredit any form of regulation.
The default assumption is that a proposed regulation benefits powerful interests, because powerful interests are the ones who can have regulations enacted.
That doesn't mean it's a violation of the laws of physics for a regulation to do something good, but if you open the US Code to a random page it's not what you'd expect to find, and if someone proposes a new rule they should be viewed with skepticism.
> Or you could just abuse your dominant position by preventing your suppliers or retailers from doing business with your competitors, outright buying them, running them out of business by temporarily dumping your prices etc. these are all both more effective and more realistic options than outright violence.
These also require the market to already be uncompetitive. If there are a thousand suppliers and retailers, you have to be able to strongarm them all or your competitor can just use any that you can't. If there aren't regulations creating a market barrier to entry then new competitors can form and you have to buy them out for more than they make in the market which in turn is more than their entry cost, but if you do this then it's profitable to keep creating new competitors to make you buy until you run out of money. You can sell at a loss but with low barriers to entry now customers or retailers can go into competition with you just to force you to keep doing that forever and lower their own costs.
Also notably such things have been anti-trust violations for a hundred years or so without requiring any new legislation (and this is still a useful check when some other regulations have caused a market to already be uncompetitive or have high barriers to entry).
> Sometimes this can be accomplished by reducing restrictions and sometimes by introducing additional laws.
But many of the laws proposed to address problems caused by a lack of competition are not even attempts to restore competition. They're commonly attempts to mitigate the damage caused by the lack of it. And these laws typically make it harder rather than easier to actually restore competition, because regulatory overhead favors large conglomerates with legal departments, reduces the flexibility that could allow new challengers to find a niche or is just literally drafted by the incumbents to create a regulatory moat.
> We should also take into account that unregulated markets are hardly ever competitive.
There is no such thing as unregulated markets. Governments at a minimum enforce contracts and property rights, and then must do so in a way that doesn't enable market consolidation, e.g. by not enforcing contracts for the formation of a cartel or allowing one entity to buy all of the land in a city.
But regulations should be directed to pricing major externalities and promoting competition rather than trying to micromanage a society made rotten by other rules that make markets uncompetitive.
