This is a micro/macro mistake. You obviously can't dump a 6% stake at strike price on Robinhood.
"The Market", at this scale, means "You find the buyer(s) yourself and work up the deal with a hundred lawyers and PR staff and hope the contract negotiation stays secret".
Actually, that's the service provided by GS, etc. They have those buyers on the other side of their Rolodex.
Well, yes. They're the ones who actually employ the hundred lawyers and PR staff. But that's what it takes, and it's not about clicking some buttons on a Web 2.0 Day Trading UI.
It's really not far from it. You don't need to do a private off-exchange sale (though you can), they do incremental execution (where you break the trade in small batches)
What is GS?
Presumably Goldman Sachs (or any investment bank worth its salt)
Well, to be really accurate, I assume GS is Goldman Sachs alone and "any investment bank worth its salt" is referred to by the "etc".
a great vampire squid wrapped around the face of humanity, relentlessly jamming its blood funnel into anything that smells like money
Goldman Sachs
Isn't that literally what institutional trading desks are for? One of the reason to use one is that they can execute a large order without impacting the market price
