The problem is that businesses have been setup in such a way that they can't just stop spending money when they aren't earning any money.
But this can mostly be fixed by law, with a law that retroactively changes all rent, leasing, mortgage, employment contracts and in general any contract that involves periodic or future payments to be stopped at will, subject to no longer enjoying the service or product.
Then they can just stop paying rent and paying employees and cancel all supply deliveries, since they no longer need those, and they will not lose any money.
Then add a temporary UBI and a ban on actually evicting from rented spaces (since the economy is shut down, and thus there would be no other tenants) so that people can still have a home and food.
