I get your argument and I appreciate it. But the nature of those low hanging fruit are more complicated today. For example, you can't just recreate Twitter, Facebook, Reddit today in your home with a couple of friends with no solid experience. You similarly can't start most successful SaaS ideas that were started in 2010-2014. Most successful YouTubers started their channels around 2008-2011. This was a time when you could make a very successful venture relying on the viral marketing by social media and Google search. Nowadays, this is over. You can go and try this same hippie way for starting a small business today but your chances of success are 1000x lower. The internet is much bigger, and it's much more centralized and concentrated and the competition is much more harsher.
