There is a lot of discussion on this, much if it heated. That said, there are a lot of essential businesses still running in the country, with relatively low spread. There are ways to socially distance and be properly sanitary even in bowling alleys and movie theaters. If they don’t try to jam them full, and people abide by the rules in terms of social distancing, things can be made much safer than back in the days of “see how many people we can jam in without cleaning in between”. I expect that we will see theaters with 50% capacity and extensive sanitation between shows. They may require patrons to wear masks. All of which will reduce transmission.
Let's say 10% of the economy is running outside of healthcare, excluding people working remotely, we've seen 50K deaths in a month. I wouldn't say that is "relatively low spread." That's substantial. Now if we reopen the economy without going through phases, what exactly do you think will happen to that death count?
And, again, its being proven more and more than the 6 foot rule is not as effective as one suspected. Even if it was, I'd highly doubt most bowling alleys or movie theaters are going to be able to wipe everything down to the level of complete cleanliness.
