Hello again Joel.
I think I can agree with you, in a pragmatic sense, with what you state
below.
I agree that any useful TOE should be able to be implemented on a (large
enough) computer. This computation can then SIMULATE the relevant or
important aspects of the universe we observe, or all aspects of other
possible universes, with their APPARENT real-number continua and infinite
sets. Godel's theorem prevents us from simulating all aspects of our
universe.

Adopting that perspective, we should be able to justify that a simulation of
our universe does not appear overly fine-tuned. At least that would suit my
aesthetic tastes.
