That's how everyone makes money. They produce a good or service and get paid accordingly.
I go to a decent number of concerts and unfortunately have to deal with Ticketmaster and live Nation. Between the Monopoly and scalpers, it is a joke how ticket prices are.
Selling VIP tickets for extra meet and greet access, or whatever is just another product. Almost every large performer I've gone to see had had some kind of vip offering. Nobody has to buy these things, but if you really like it and can afford it, you do.
The artist does not make extra money off of inflated scalped tickets. It's dumb that it happens, but Swift was one of the few people that did push back against Ticketmaster for allowing the practice.
Yes, she built an empire off of her fandom, that's how that works.
