A venue is more than having a place, it's having everything necessary to handle an immense volume of people gathering, acting, and dispersing from a single location in a safe and orderly fashion.
That's a 70,000-seat stadium [1][2]. Arenas (5 to 20k) can be built for a few hundred million [3].
Unfortunately, that would mean either nosebleed ticket prices or rationing tickets to fans. The former would earn the fans' ire. The latter reduce the artist's revenue.

Ticketmaster: oh the tragedy, our shareholders..they might not get as much profit! housing! think of the homeless! if you build this arena, it will sit dormant 95% of the year, this space could be used to house homeless, so VOTE NO! on question 45 to protect $CITY's homeless!
