One obvious reason is that immunity via infection is significantly inferior to that granted by vaccination. Also, please don't exaggerate; nobody is being "forced into" vaccination.
To the extent that restrictions are being put in place, that is happening to save lives. I for one am glad of that.
Ivermectin, btw, which you misspelled, is not a good or even average treatment for covid-19.
