my view of capitalism is that you can't remove the market. it will exist with or without you, so if you have some control you should incentivize the things that are better for everyone.

To me I think it's possible for Netflix and Amazon and whoever to exist and make a lot of money, but also not have nation-state level power. The latter is something we haven't decided we want yet, but I think we'll come around. If there were even just very small controls (that worked) on the size of a company, or how many industries it can go into, then things would look differently. But when we let so few companies consolidate so much power through money, the status quo is a pretty natural outcome. Imagine a world where there were regional amazon.com's, because we just decided at some point they got too big. Same for google. We'd have actual competition. Tech enables market consolidation in ways we didn't expect and we have to do some actual work to fix it.
