Yes. The world contains a vast amount of compressible order for which
the simplest explanation is physics. Either your hypothesis is that the
unicorns dreamed all of physics up to this point - which is simply
existing physics plus "unicorns", an unjustified penalty of Kolmogorov
complexity - or, even worse, the unicorns dreamed something that
coincidentally looks exactly like highly ordered physics. Either way,
physics alone is a simpler hypothesis with a far greater prior probability.
