The solution is that society shouldn’t make people dependent on any single means of income for survival, not that no one gets rejected/disbarred from any occupation ever. Ultimately any negativity towards a person lies along a spectrum, and it’s important not to lose sight of the degree of harm involved.

The revoking of professional licenses is not (and should not be) intended as punishment of the individual in question, but rather limiting the damage to society of their recklessness.

That can sometimes be a slippery slope of its own, but I will argue that it’s a somewhat different slope (the “for the greater good” slope) from the “totalitarian government hates nonconformity” slope. Sometimes they intersect though.
