You're missing the point of a lockdown. It's not solely a question of whether virus is spreading inside the doors of the business. It's about whether the virus is spreading in the Uber on the way to the business. It's about whether people are congregating outside the business. It's about whether employees have to take mass transit or carpool to get to work at the business, during which time virus spreads.
And yes, the hard lock downs do smash the virus. "Several hundred cases per day" in places with populations in the tens of millions -- that is indeed smashed. France, for example, when from over 4,000 cases per day... Over the last 2 months, down to 400-600 cases per day. The population of France is 3 times the population of Florida -- So that would be the equivalent of Florida having only 100-200 cases per day, as opposed to 10,000 per day. Yes, I'd say 95-99% fewer daily cases is smashed.
Yes, let's use Spain as an example. Perfect.
Population of Spain -- 47 million.
Population of Florida -- 21.5 million.
Spain case peak: About 7,800 Florida peak-- unknown at this time, but maybe about 11,000
Spain 7 day average through June -- About 350 cases.
Now in July, a couple months after the end of the lockdown, cases are starting to rise again -- They are back up to about 1400.
Current in Florida -- 11,000 on average.
So... population of 47 million -- 2-3 months after end of a hard lock down, only 1400 cases.
Florida, population of 21 million, 2-3 months after end of a very soft lock down, 11,000 cases.
So Florida has about 20x more daily cases on a population-adjusted basis.
You're missing the whole point --- So you're saying, there is no difference between 500 cases and 10,000 cases. No difference between 300,000 deaths and 3,000 deaths??
As you just said -- Lockdowns suppress spikes --- So if you suppress the spikes and keep them low enough, while you develop improved treatments and vaccines -- you save lives!!!!! Hundreds of thousands of lives!!!
You're saying that since a lockdown would only save 90% of the potential lost lives, since 10% of the deaths may still occur... we might as well just give up and let everyone die??
There you go again. Since it's not practical to eliminate 100% of the virus, we shouldn't even bother taking steps that can eliminate 90% of it????
