We have forgotten the deeper reasons that certain things were prohibited or discouraged, assuming that these rules were only there because of a belief in a religion society doesn’t follow anymore. That was a naive view and it turns out that many “old” rules are actually pragmatic social codes disguised as beliefs. This isn’t limited to a particular tradition, either: pretty much every major religion has frowned upon things like gambling.
And so in the absence of any real coherent philosophy that aims to deal with complex problems like gambling, addiction, or excessive interest rates, you’re only going to get an expansion of what is already dominant: markets.
Don’t expect this to change until knowledge of ethics and philosophy becomes widespread enough to establish a new mental model for thinking about these issues.
If we want less money around college sports there need to be a lot more rules all over the place to make sure there is less profit to be had. Or we could just let people get paid for labor even though they are also students, which is the fair things to do and it's something we do in just about every other context.
