How very bold of you, to be telling Nature what it can and cannot do.
I think the point is rather that discontinuities (and in particular
singularities) often make physical models of the natural world hard
to use, therefore we prefer our models without them.

The discontinuities and singularities are only in your conceptual and
mathematical constructs, not in the physical world. It's not that
discontinuities often make our models hard to use, rather that they
always make them inaccurate. Again, show me one example of a true
discontinuity in nature. One reason you won't be able to is that if
these existed, then measurement with unlimited precision would be
possible. Another reason is that you could then violate conservation
laws.
I am not bold, I am only articulating what appears to be a physical
axiom, because observations warrant it. If you have evidence to the
contrary, then i will be very interesed.

If my experiments cannot report singularities, and (even
if experiemtns did) my models are impossible to work with
in the presence of singularities, how am I supposed to tell
whether singularities exist in the physical world or not?
