Physicians were not smart. They had licensing and liability imposed on them after quacks killed too many people.

Civil engineers were not smart. They had licensing and liability imposed on them after bridges fell, dams burst, buildings collapsed, killing many people.

Software developers will not be smart either. They will cry about not wanting liability and make accusations of gatekeeping until something bad enough happens (Crowdstrike isn't it; not enough people died as a direct consequence) and licensing and liability is forced on developers.

And, to echo sentiments voiced by other replies, the anti-government hyperbole is more kooky than persuasive.
