I’m big into sports but this seems like a reasonable take – it’s already the case that none of the good youth soccer leagues are affiliated with schools, and it’s easy to see how you extend that model to other school sports. Also, having the NCAA be the minor league for the NFL is enriching NFL owners at the expense of our university system. The downside, of course, is that we’ll exclude children whose parents can’t afford to pay for club sports, which generally I’m in favor of moving public goods (like getting children active and learning how to cooperate) to be paid for by government rather than private enterprise, but I get it. I’m not sure how it relates to trans athletes in sports, though – you’re just kicking the can down the road to a bunch of laws and lawsuits about discrimination and participation in club sports rather than school sports.
