I never once have ever wanted my tax dollars used to pay for some asshole billionaire’s stadium. I’ve always voted against it when able to, but we know that does fuck all in this dystopia.
When they did this in Seattle, it was voted down. So, the city council got the state legislature to pass it as state law to override the vote. Then, the demolished the Kingdome, which had been the largest concrete dome stadium in the world and didn't get paid off until 2015.
Considering that publicly funded (or royalty funded, which amounts to basically the same thing in feudal systems) sports has been a thing across all civilizations for all of history, I doubt the future people will blink an eye.
Seriously, I'd argue the solution here is to actually go even harder into it.
Club sports, build smaller scale stadiums and arenas for more localized teams and create a part-timer's bracket for folks to get compensation while still being able to keep a day job.
Reserve the big time stadiums for big time games like regional title matches or tradition games like the subway series and home run derby.
Plus it'll more or less instantly suck a lot of energy out of far right movements since so many of them tend to be animated by male sedentariness, at least in the modern day.
No, they will either be too busy fighting whatever the current dumb culture war, or they will be melting their brains with endless consumption of AI generated media.
