That's a really stupid analogy.
Assuming the blind crew gets the plane in the air, you have about a 90% chance of dying in a fiery crash.
Even if there are 1000 COVID-19 infected patients standing in the immigration line at the Cozumel airport, sneezing in to every new arrival's face, your chances of dying are still under 10%.
I know this is about a week old, but saw it re-quoted earlier today, so highlighted the one part. We keep focusing on MY chances of getting it, or MY chances of dying. Certainly that's a worry, but the bigger issue, and I'd argue, personal responsibility, is how much are my actions increasing the likelihood OTHERS will get it? Using your statistic, if I caught it in the immigration line, I may only have a 10% chance to die, but 5 days later when I'm asymptomatic, and I sneeze on the three old shop workers with underlying medical conditions, and they catch it, their risk of death is a lot higher. That's my big problem when I see people saying you're infringing on things like my right to liberty or freedom. Your liberty or freedom doesn't operate in a vacuum, it potentially has effects on others and we, in my opinion, have to be cognizant of that and also be responsible.
The truth of the matter, for me at least, is I feel I have a responsibility to take measures that not only limit my risk of exposure, but that of others as well. No one really knows for sure how bad the virus has spread there. However, we do know that increased social activity and interaction will increase the number of infections. The medical infrastructure of Cozumel is such that I don't know how well it can survive with a huge influx of patients, and knowing that if I may have potentially played a role in that collapse is something I struggle with, especially when I weigh that against my reason to go there.
Having to go out to go to work or to buy groceries is a pretty essential activity. Going diving down in the Caribbean is not (though I really really want to). Donate money if you really want to help without having the potential to be part of the problem of spreading the virus. If you spend $600 in your 10 days eating out in Cozumel, send $30 or $40 to each of the 10 restaurants you would visit. There is virtually no cost for them (food, etc) to net out that $30 or $40 and use it to help maintain their business. Save your smiling face for the next visit.
