As a parent far on the liberal spectrum I am just fine with proper functioning government regulation, and the job they did in the 70s/80s/90s was perfectly fine.
You are obviously arguing for zero-regulation, or you think you are in the libertarian sense. I always like to ask libertarians if they think murder should be illegal, which they usually do. Well, guess what, you are in favor of government regulation, it simply comes down to what line in the sand you are drawing that obviously is convenient to your own self interest.
If the US does something like the EU DMA, do you regulate all app stores for content?
Exactly how do you do either in a way that the government doesn’t come in an regulate content that they don’t like?
