Personally, I'm less concerned about gyms. People in gyms are adults and can theoretically stay 6-ft away from each other and wear a mask. I've seen high-impact classes like kick-boxing being held outside in parks for better airflow. Driving activities underground however, has well understood unintended consequences of causing violence and disregard of health rules, as we know from prohibition in the 20's and the drug war since the 70's.<p>The uniquely American issue, is with bars and clubs being closed. In the land of big houses, everyone knows someone with a bar in their backyard or basement. Keeping bars closed now, when everyone is fed up with the social isolation (sorry, Zoom doesn't cut it) just means actual underground speakeasies serving alcohol aka house parties. Where dedicated gym rats <i>aren't</i> drinking alcohol at the same time they're at the gym (it hurts gainz), and are <i>can</i> be more responsible for their actions, people on alcohol <i>can't</i>. I'm not saying that to excuse drunk people's behaviors, what I'm saying is that trying to get drunk people to stay 6-ft apart and wear a mask is an exercise in futility.<p>Since people are gonna be drinking anyway, <i>especially</i> during a pandemic, and a recession, and in the face of great uncertainty, <i>and</i> on the cusp of a presidential election, what's needed is to <i>open</i> the bars, but require patrons scan-in via phone app using the bluetooth-based contact tracing (PEPP-PT), or else face suspension of liquor license. By making it required at bars, you get around some of the privacy issues since those that don't want to, can just not go to bars. Using bluetooth-based tracing gets around issues of using GPS-based tracking, and also helps amplify the effectiveness of an under-funded contact tracing corps by providing a technology based solution.<p>This is imperfect, but perfect is the enemy of the good, and even done imperfectly, contact tracing can very successfully drive Re (the local effective value calculated from a diseases' R0) down below 1, at which point the disease doesn't continue to spread and the pandemic can be controlled. For a disease like COVID-19 with an R0 of 2.5, it doesn't take too much to drive it down.
