More available solar energy. More available minerals. Few pollution worries (sortofa problem just now on earth.) Supports a far larger population in time. Freeman Dyson's explanation (pre-Musk), that it gives us redundancy because humans make mistakes, is of course unappealing if you think that civilization and the earth's ecosystem is indestructible, but many don't think that anymore, and the number of ways we could put an end to ourselves or our civilization seems to be growing. There are whole books on this, of course.
