Problem is we don't know of any natural processes that randomly select "real" numbers. Anything we can do or measure in the natural world has limited precision, not infinite precision like real numbers have. If you believe some natural process *really* selects "real" numbers (even though we can't measure or determine in any way *which* number), that's just a matter of faith.
