>Invasive tracking is the point, not the cost. It's anti-consumer.
The last (and likely the last) time I went to an MLB game (not the Dodgers), perhaps six years ago or so, I was required to install a smartphone app when I purchased my tickets, keep that app on my smartphone for before and during the actual game. In the several months after buying a ticket and seeing the game, I received no less that 100 spam email messages (I was required to provide an email address as well) from the team's "partners."
What's more, not only was there no option for a paper ticket, if I left my seat during the game to get food/drink, I was required to have my smartphone and present my "ticket" via their app to security personnel when I returned to my seat. Every time.
As I said, even though I was (and am) a life-long fan, I will never go back to the stadium to see a game. It was far too invasive and inconvenient.
Edit: I'd add that I couldn't even block emails (which I routinely do at the server for other emails) from those "partners" because there were emails that were required to obtain my tickets. That isn't me not wanting to "learn" something, that's me not wanting to receive multiple spam emails every day from the same source.
