There's a reason why most TLDs are owned by giants like Google or Apple or hoarded by companies Donuts, the cost of entry is so absurdly high that it's impossible to start from the bottom. Natural monopolies (an economic wankery term for when the cost of starting competition with something is so high that there will naturally be few or only one winner, eg. Power companies, ISPs, rail networks) are extremely prevalent in tech because of how expensive it is to start from scratch
