That's kind of the point, though. Minds are nonphysical things, and
there is no apriori reason why physical things need to exist for minds
to exist.
You have evidence for disembodied minds?
That's not an apriori reason. Assuming you're in principle OK with the
concept of a brain in a vat (which is a disembodied mind), then the
you too do not have an apriori reason for the existence of physical
things.
I don't see that a brain in a vat counts as a disembodied mind. Do you mean
a brain that has no environment to perceive or act on? I would deny that
such an isolated brain instantiates a mind. On the other hand, if the brain
has sensors and actuators operating, say a Mars Rover, then it isn't
disembodied.

Yes - I know your argument. In the BIV scenario, the environment could
be simulated. Basically Descartes' evil daemon (malin genie)
scenario. Nothing about the observed physics (bodies and whatnot)
exists in any fundamental sense.
But then "fundamental" loses it's meaning. The BIV+Enviroment in the
vat constitutes a world. The "fact" that it is implemented in some
other world becomes just magic talk, like the world exists in the mind
of God.
