The stereotypical SV playbook is to enter a market, don't give a crap about the local regulation or laws, try to get big by using your cheap money to outstrip to competition and do rent-seeking when you are the largest.
Also, a lot of startups are solving non fundemental problems.
We should be spending all that engineering effort fixing things like climate change, food security for the global south and a way to deal with the aging population in the western world instead of thinking about algorithms to get more clicks on ads.
Also, there are many startups building stupid junk to capture a piece of the pie but also many startups working on real problems.
This whole comment is a reductive cliche at this point.
Please start a company to work on fixing climate change, food security, aging, etc.
