The difference being the lottery system. When scalpers know they are competing against other scalpers, they know they will corner the market and everyone will pay. Which is how they make money.
With the lottery, a good chunk of those systems are going those who would be willing to pay markup for them, but didn't. So the lottery does double-duty - it kills scalper supply and demand for scalped units.
