I wouldn't expect there to be law given that the government as never responded to a pandemic in the way that it has now. Your argument that it is temporary may be persuasive, but I wonder if that disappears if the shutdown order is long enough that it results in the business failing. Your point of the hurricane is not persuasive, in that situation, the hurricane does the damage, the government order is ancillary. Here, the shut down order is more of a direct cause in the business harm.
