Not even necessary. Causality only would show not to be bound by
light speed, as was thought until now. Before Einstein many people
thought that, and didn't seem to have any problems with it.

Another question: is there any inherent reason why our velocities are so
*much* lower than light's? There is a story 'if light went with 55 mph',
which made me wonder.
