I think you're overlooking the cost of regulation and safety-first thinking on society as a whole. Especially as we have a wealth of recent examples as to why the American regulatory regime has failed.
Candidly, this attitude is precisely is how we got into the regulatory hell where we are now.
In principle, I love the idea of licensing. I really do. Take a standardized, state-provided exam to show competence in some area where there is a compelling public interest for regulation, and this grants you the legal ability to exercise that skill.
Want to practice medicine? Exam, plus some number of hours of supervised practice before you can treat patients independently.
Note the complete lack of a schooling requirement -- if you can demonstrate the knowledge during examination, you should be permitted to apprentice under a licensed physician.
In practice... this doesn't work, at least not right now.
Americans as a whole no longer have any confidence in our regulatory frameworks, and rightly so, because they inevitably become weaponized against the very people they are supposed to safeguard, due to the combination of corporate lobbying, and a law enforcement system that rewards "finding and harshly punishing transgressions" over "serving the public interest"
Imagine you want to open a restaurant.
The way it should be is: take an exam to show that you understand how to safely prepare and serve food; have your kitchen, which could be in your home, inspected before you start operations; and at truly random intervals, an inspector will pop by to check in on things.
The way it is: wade through months, if not years, of chasing down permits; buy expensive equipment mandated by constantly-changing laws pushed by massive corporate entities that can afford the compliance game; and deal with very-much-not-random inspection regime which can (practically) shut down your livelihood if you look at them funny.
Until we fix oversight and our culture of punishment, we should be looking to remove regulations, not add more.
