I don't often forward posts from the Extropians list, but this one is so
good that I just had to do it.

You may be thinking of a specific scenario for uploading that is more
restrictive than necessary. Broadly speaking we use uploading to refer
to transferring our minds from their current biological brains to some
kind of artificial system like a computer.
Our minds are already confined to a system which is less than the
universe, namely our brains. Transferring them to a computer does
not have to limit our options to move around or access the universe.
Of course if the computer is gigantic and needs massive power feeds
then moving it will be difficult, but in principle one could have
a small computer and move it around easily.
Even without that, I don't see what the problem is with telepresence. In
a way, all of our perceptions are mediated already by sensory modalities.
Our brains live in a dark, quiet, wet place. That is the reality.
It is only by means of our senses that we get the illusion of being out
there in the world. In a way, our bodies are a form of telepresence,
operated by our brains, huddling safe in their little caves of bone.
Uploading also does not necessarily mean operating in virtual reality
independent of the physical universe. Of course if the new system is
super-fast, it may not be desirable to spend too much time waiting
for things to happen in the physical universe, so naturally we would
turn to some form of VR which can operate at a more convenient speed.
But manipulating the physical universe will still be a necessary and
important activity. Even if you spend most of your time in a VR there
needs to be construction, maintenance and defense of the physical
substrate which runs the VR.

Now I think you are getting even more specific and picturing a very
special kind of VR, where you have fantasy wish-fulfillment. I
suspect that this will be a popular form of recreation but will not
be the only mode in which people interact in the future.
