Not sure about other countries but the US bailout money are loans, not gifts. These businesses are taking on massive debts to keep afloat. The longer this goes on, the worst shape they'll be in when they do reopen. Since the loans will be forgiven if they default, businesses have some incentive to take the loans now and just close up shop later. It'll be interesting to see what happens in a month or two (regarding defaults and bankruptcies) when it's expected that most states will start reopening.
Aren't all successful companies start their business from taking massive loans? And there's nothing wrong with that. That's how business has been done for more than a century in the Western world. Why should we suppose that they would choose to declare bankruptcy right away? Some of them will do just that, of course, but, I'm sure, most of them will strive to make profits(and will succeed in that, imo).
