If there was a free test of COVID that could judge with a high degree of certainty tell if you were infected or not, this would go a long way to assert your point. But since rapid tests are expensive, hard to come by, and not free (for the gov), we have to live with trade-offs.
The sad point off this is that you're contagious when you're still asymatic, so even those wanting to do the right thing cant prevent accidental spreading. All we can do is reduce our transmission rates as low as possible. Vaccines did a great job of that pre-omicron and though Omicron seems to spread just as freely in vaccinated populations, those with vaccines had far better health outcomes. Who knows what date will throw at us if/when another significant variant mutates into our lives.
