The catch here is this will potentially enable you to hire those 10x people. Even at reduced productivity, 80% of 10x is more than double productivity for 100% of 3-4x people, and perhaps this work environment will foster other people to increase their productivity as well.

With the right people and product, I see this as the ultimate weapon against big tech, most of which will have shareholders that will act a lot more conservatively when it comes to risks compared to startups.

This is not something big tech will be able to accommodate in the current macro-economic environment, no board will approve basically a 20% salary bump to all employees and while risking a potential drop in productivity.
