That is also one of his core arguments on his book "Zero to One".

To be fair, he is not the only one to think like that. Every "captain of industry" needs to be paranoid against competition. It is a basic survival instinct. Just look how much Steve Jobs freaked out about Android and Windows. Or how Alfred Sloan bought or merged every possible competitor. Or the history of Nabisco, the steel industry, Microsoft, AT&T, etc

And that's not a bad instinct which (in a perfect world) drives innovation and lowers prices for customers.

But that only works if the competition can not be simply bought out which requires effective anti trust laws before they get so big that "nobody" can compete.

I firmly believe that it's better to prevent a company from growing too big than breaking it up after the fact.

Almost everybody profits from smooth and constant enforcement.
