I think a lot of what you said doesn't take into account how actual reality works. I think the system dynamics you're using may be purely academic. I was saying one person as an example...but America has millions of undocumented people that snuck across the border here. Do you honestly think other countries don't? Borders are very fluid. Humans are social creatures by nature. They're going to come into infectious proximity of hundreds if not thousands of people a week at grocery stores, restaraunts, gas stations, bars, salons, etc. Also theres's science showing corona virus stays on surfaces for days which means if they cough on a surface like a doorknob that can spread to people they weren't in contact with. Contact tracing is useless. Like I said.. once again.. youre just lucky and are patting yourself on the back too soon... or your region has reached some form of herd immunity.
