> Nobody would have lost any money or bitcoins.

That's not entirely true. The current crop of Lightning Network nodes rely on their host being up for the safety of their channels. If their node is not contactable for more than 24 hours they risk having their money stolen.

Large changes in the network graph has been shown in Bitcoin to take quite a while to sort out, due to the way the rumoring network attempts to find stable and reliable peers. This is still a substantial problem now, as there's only a few thousand listening peers that can accept incoming connections out of over 10,000 total. If only those nodes were remaining online there would be substantially reduced capacity to relay blocks and transactions for a period.
