That's hardly an argument.
Einstein already understood that if the collapse was a physical
phenomenon, and if special relativity was correct, then locality would
make a wave possibly collapse on two different eigenvector, like
sometimes finding literally the photon going in both hole. In that
case, the energy would be double, and the schroedinger "diffusion" of
the wave could be used to ... create energy. A quantum perpetual
machine could be constructed, and, pace George Levy, but following
John Clark's quote of Eddington, we can stop here ...
But the collapse is not physical, it belongs to the mind of the
people, fungible and then differentiated, in the infinite tensor
product, which, with computationalism, should be a mirror of the fact
that we are indeterminate on infinitely many sigma_1 sentences, where
the ortholattice structure is determined by the logic of self-reference.
For a computationalist (who thinks), the collapse is not real, but the
wave is not real too. It is itself the product of a Moiré effect on
all computations.

Yes, and as the branches multiply, so does the energy.
I doubt this, but eventually this will depend on how we define
energy. I doubt a photon needs to double his energy to go through
two slits, and I doubt Shor algorithm needs energy to handle 10^500
parallel superposition state. Energy is a local relative (gauge)
notion, which I am not sure can be easily applied to the whole
configuration space, which energy can be put a zero.
Of course with computationalism there is only an arithmetical
reality, and all physicalness is a view from inside. All branches of
all computations including the one with oracle are run in the
arithmetical reality, and it is clear, imo, that energy is only an
internal relative notion. Of course we need to justify why the
reversible computations win the limit measure "game".

It seems, yes. In our branch. But not in the physical reality as a

Energy is not constant in the MWI multiverse.
Energy is not constant in a general-relativistic universe.
I believe energy is approximately conserved within a branch of the
multiverse, in the MWI view? The "approximately" being because
branches are only approximately defined?
