When those other professions started out the Internet didn't exist so you needed a physical school to learn. The whole industry got built that way, standards got established etc. it isn't bc they are trying to artificially control supply (at least not initially). would be hard to change all that now If software were to impose such restrictions it would be much harder to justify other than "we want to preserve our high salaries". When laborers formed unions they were genuinely exploited in many cases. Not sure how you rationalize a software engineering union...
