I would guess that Lacrosse and Water Polo were conducted in publicly funded venues as well. Probably not in 60 million dollar venues, but funded by taxpayers as well. Like this one, at their choice as well. It may not be wise, but they were not coerced, and unlike your comparison to Obamacare, there are no constitutional questions about a school district choosing to do this.
Naturally, ten years from now, when things go south the same conservatives will be whining about "excessive" spending.
