Not all art needs to be preserved. Everything will be lost eventually, and efforts should be withheld for the worthwhile. People that don't work with preservation usually have a kneejerk feeling that we have to save everything for all time, but it is not feasable nor is it commendable.
And since we're apparently only dealing in absolutes - would we be in bigger trouble than we'd be in if no art, nowhere was kept for any amount of time?
well you don't buy a server, you basically buy a key to accessing the server. It's no so different from a website in that regard and websites also shut down with no notice.
it's just that web pages are easier to backup than game servers.
