Stir how? In a computable way? You might want to try to formally describe
what you mean.

Pull out at random? The topic of this thread is precisely: where does
the randomness come from?

Why? Suppose every 2^n-th number in the bag is n. Then each number is
repeated infinitely many times. But why should P(17) equal P(42)?

There is an instructive little exercise: Try to precisely describe
a probability distribution on the natural numbers such that all are
equally likely.

Then try to precisely describe a probability distribution on
infinitely many patterns such that all are equally likely.
