Spores are highly resistant to oxidisation, but for a spore to produce more spores, it has to develop into a bacterium, and bacteria are not resistant to oxidation. This is not happenstance - spores can be resistant because they don't do anything, they are just simple storage containers for DNA and the minimal machinery to use it, whereas a complete bacterium has to do much, much more. So, this is not a model for life which can exist in a permanently oxidising environment.
