So build faster and better than YC to defend society|humanity against YC portfolio companies (not all, of course, just the harmful ones) until politics can close the gap. There is no speed limit.

It's very hard to believe that a company setting out to fight against one of the major "legs" of the stool of the US Economy is going to be playing on a level playing field against companies whose mission is to strengthen those legs.

A company fighting that will never be funded by anyone significant.
I never said it would be a company, or a business. You might call it a project, an effort, or something similar. The name is not important, only if it is achieving its target outcome.
