you can buy 1 ticket, but then you can't change the name.

It does not prevent scalpers altogether, but it makes it harder and less profitable.

Generally, people do not want to go to an event alone, you'd go with a friend, partner, spouse, whatever.

So the scalper's profitability calculation goes from "buy 10 tickets for 100$ and sell them at 10x price to anyone" to "buy 2 tickets and sell 1 of them at less than 10x to people who want to attend the event alone". The profitability went from 10000 to less than 80.
