Here's my mathematician's perspective on this, having used CVS, Darcs, and Mercurial a lot before Git. One day, angry by the situation with Bitkeeper, Linus Torvalds thought to himself "Let's pretend that Sha1 hash collisions don't happen; what can we do?". The result that he deduced from this assumption was a distributed revision control system that was an order of magnitude more efficient than any of the competition, and this was absolutely critical to its success. And Linus probably just assumed the Sha1 problem could be sorted out later (like it was [1]).
