Wikipedia relies on volunteers to do updates, corrections, and repair of vandalism. Storage is cheap but their time on this thankless work (just look at this thread—and we're relatively civil!) is a limited resource, and the thinner you spread them, the more unusable (outdated, mistaken, and actively misleading) the results will be. If you want a boundless supply of crap content, the union of everything anyone ever bothered to write, we already have one: the web.

If tyrannical admins didn't chase away all possible contributors by deleting their work, perhaps this would no longer be an issue.

It's not the admins. There are relatively few of them, and they really don't nominate pages for deletion very often. When a page is nominated, it's the community that argues and the admin only deletes if there's clear consensus. The problem is that deletionists flock to AfDs like it's Mecca, and inclusionists are too busy writing content.
