> If you keep losing data to power losses or crashes, perhaps fix the cause of that? It doesn't make sense to try to work around it.

Ponder this notion for a moment: there are problems within one's control and problems outside of one's control.

For example, we can't control the weather. If it snows three feet overnight you simply have to deal with the fact that you're not getting to work today.

Since we can't simply stop hardware from failing, we have to deal with the fact that hardware fails. Your seventeen redundant UPSes might experience a one in a trillion cascade failure. It might take the utility ten minutes longer to restore your power than you have onsite generation.

This is not a class of problem we can control or prevent. We fix these problems by building systems which withstand failures. You can't just will electrons out of the wall socket, but you can build a better disk or FS that corrupts less data when the electrons stop.
