Oh, just lol. I can see the nuances of the engineering choices aren't getting through here.
That very choice is a critical part of why there aren't many cheap EVs on the market. If you'll recall, Eberhard was trying to keep costs down so that ordinary folks could afford the vehicle. Smaller motor plus gearbox costs less and reduces other costs as well. Elon changed the engineering goals, forcing the roadster to be priced yet higher.
A large, custom motor "solves" the problem inelegantly by replacing an undersized mallet with a sledge, as you'd expect from a moron. Correspondingly larger IGBTs, larger switching losses, more battery capacity lost to needing to parallel vs series for feeding the larger motor a lot of current. There were and yet remain many downstream negatives to that decision.
As for the rest of the market following, why are you surprised that the same market which kept saying "10yrs away" also couldn't be imaginative enough to innovate?
It's obvious you don't want to shift from your position either, the funny bit is that at least one of us here has evaluated merits vs problems with any technical background. Keep on drinking that corporate Kool aid.
I remember reading about that too. I wonder where the truth lies in all this.
