> No single human needs to hold a billion dollars or more. There is no good reason to allow this sort of thing

Just utter totalitarian garbage. What make you, or anyone else the arbiter of someone else's legally obtained property. Right to property and ownership is enshrined in the constitution for this exact kind of demagoguery.

It's another thing if you called for stopping wealth accumulation by illegal means, and those laws already exist. But what you want is the ability to thwart someone else's basic human right to property - modulate it with populist moral sounding immoralities of upper-limits. FYI, YC's portfolio has a net worth of $80B [1]. Do you want to pitchfork against the YC folks now - who are enabling HN?
