I think that is wrong way to think about it. If, say, we do enforce some "barrier to entry", it would probably be some education and certification to be eligible for software development. The SJWs will make sure that they will be prioritized to be eligible for those certificates, even if it means to change the eligibility criteria to do so. And then they can basically use it to kick everyone out of software development, except for SJWs. I think we should keep it as it is and wait it out. They will find something else in a couple of years and move on.
