I hate semantic and pedant arguments on the Internet but this is worth it:
We don't legalize things in America, we illegalize things.
The constitution doesn't give us rights, it actually takes them away so our government can operate.
We give freedom lip service in this country but if you truly believe in it this is what we must drill into people in civics class and in discourse.
This is in fact what happened with sports betting. They wrote a law making it illegal. That law got struck down, so we are back to the default which is it is legal.
We can make it illegal again to address the court ruling, but it's an uphill battle.
I don’t know what you think was gained by this argument.
Sports betting was effectively illegal, and a number of people lobbied aggressively and pursued lawsuits to overturn the status quo (de facto federal ban) then a huge number of efforts to permit it at the state level in a bunch of states.
All of these efforts are completely adequately described as “legalization” efforts.
Yes, we can change the new status quo again. And we should.
