It is reasonable. The universe just turns out not to work that way. That c
is a limiting velocity for all phenomena is not something we can deduce a
priori. It's only on the basis of experimental evidence that we believe it
to be true.

It can be deduced a priori that a discrete universe can only have one
speed. That speed is c. Nothing moves faster or slower. c is not the
limiting speed. It is the *only* speed. Certainly at the macroscopic
level, we can measure a speed that is less than c but at the
micro-realm it consists of a series of jumps interspersed with rests.
All the jumps occur at c.

By the same token, it can be deduced a priori that there is only one
interaction time in a discrete universe. One man's opinion.
