I think you've got a point there, if I'm reading you correctly: If Robinhood (et al—sorry RH you're the de facto stand-in now) can't meet the standard of keeping up with the ... other cars in the race... then they shouldn't be allowed to enter. In that case, the analogy helps since most races have minimum qualifier rounds before you're allowed to enter. I've got no arguments there. But that's the kind of thing RH [et al] were founded to confront or change, wasn't it? Or were they just circumventing previous regulation about market interfaces? This is where we get into the weeds and me out of my depth.
