Sure, there are other solutions, and you've given examples of decent ones (rent holidays, mortgage jubilees, etc), and in a better world, we would have undertaken them. We don't live in a better world, finance has a stranglehold on our politics, and PPP was a better alternative than no-PPP. There's much to criticise it, and I don't think it was the best among all possible options, but I do think it was vastly better than nothing (Or just paying people through UI, while their employers fold).
