Yeah a very small few who have a few hundred quid in their account would struggle. If anyone's in that position they're doing something badly wrong though and will need to rethink if their business is actually a business after this
True to a degree, but there's also a timing issue. If you work on staged payments for example you can be in the hole to five or six figures just before you get paid for a stage. A weather delay, problem with a supplier, people not turning in etc etc all add costs and are notoriously difficult to predict. Any or all of those happen just before the curtain was dropped and you cloud be in big trouble.
As @superspread said, I can think of a few times over the years where I'd be in deep sh1t if this happened at that point. I can guarantee under those circumstances with a choice between loosing everything and working at risk of getting or spreading the virus I wouldn't spend a second thinking about it.
