Actually, we do all benefit when small businesses profit enough to stay around. For your line of thinking to be correct you would have to believe that you and your business exist in some kind of vacuum with magical leprechauns as customers and suppliers and a workforce who just appear when needed. If the small business that makes the inputs I use for my product, or the inputs my suppliers use, or their suppliers use.... goes out of business it impacts me and every other business owner in our industry no matter how well run. If all of our customers can't afford to buy our products because 50% of them lost their jobs because their companies went out of business, that impacts all of us. If you as a customer now can't purchase the products you need because someone in that chain went under, it impacts you. There is tremendous value to all of us from having a rich ecosystem of small businesses around us, even if we never see a dollar of their profit.
Should we subsidize small business forever in the way we do farmers? Absolutely not. Should we do something to ensure a significant chunk of them don't go away, hurting all of us, due to a one-time unprecedented event? I think we're all better off from taking that step. And I believe that despite running a business that has enough resources to survive a downturn, is unimpacted by COVID and doing quite well and will not be using any of that aid.
If your "business" is personally trading then I guess I can see why one might start to believe that they can stay hunched behind a screen in a windowless room all day and massive disruptions to the rest of the world can be ignored. If you run an actual business with employees and supply chains and customers....that line of thinking is patently absurd.
