For a given architecture, perhaps.  But the constraints on traditional
electronics are not exactly the same as the constraints on photonic
computers, neither are exactly the same as the constraints on quantum
computers, and none of them are exactly the same as the constraints on
some architecture we have yet to discover or invent.  You implicitly
rule out any possibility of that last category without proof; based on
historical evidence, you are probably no more correct in doing so than
for someone in the 1930s to declare that the limits of vacuum tubes
dictated the limits of the best physically possible computers.

Even if we were to constrain ourselves to traditional electronics,
Moore's Law has been pointed out as not necessarily holding steady -
and it's been an economic law, not a physical one.
