You get much more leverage when you day trade vs holding overnight, for one. But my argument was trading vs job, any style with asymmetric payoff will do.
Some need 6 figures, some need 12 figures, and for some it doesn't matter as they will never make money. You can, as a daytrader, make a few million a year.

It's doable but I wouldn't say easy. To make a six figures a day in your account you'll need a sizeable account to start even with 4x leverage. Most newbies don't have accounts that big, at least not to start,
