I agree that opening up in a dumb way would let the virus rip through the population.
But we now know that surface transmission isn't as big a deal, and that spreading is much less likely when there isn't sustained contact. We also now have everyone wearing masks.
Given those things, I would think that any shop where you ordinarily go in for five or ten minutes and don't touch a bunch of things (shoe repair, sporting goods, NOT bookstores) would be very low risk.
Sure, if the shop is too cramped, don't open. Stick in some proviso in the order that nonessential businesses can only have 1 employee for every x square feet.
