The current system without wealth taxes already largely divorces labor from equity stake. Unless you're one of the relatively few tech or office workers who get equity compensation or have a large savings rate, you currently don't have much of a stake in any means of production.
I'm not disputing the claim that few people are able to save and invest into having a stake in the means of production.
However, if your goal is to increase stakeholdership, how would a policy that explicitly disincentivizes that behavior fix anything?
