"Almost everyone should get vaccinated" does not mean the government should coerce everyone into making the correct medical decision by barring them from employment or access to private establishments.
Absent a very compelling reason, people should be free to go against medical advice. People have the right to do whatever they want with their bodies. People have the right to make the wrong choice.
In this case, the reason given for overriding that freedom was a highly specious argument that the unvaccinated were putting other people at significant risk. That argument did not pass the smell test from the very beginning.
