Who wants to live on Solaris?

Let's assume that computational processes can be accomplished by a phase change in matter to a plasma state. Then, this plasmoid could be manipulated by EM fields allowing one to upload something into it. This would render computation in possibly its highest form.

Now, the technicalities aside, which I can't really address in public, wouldn't life on one's personal plasmoid avoid death entirely? Technically, free will would be solved, the present would continuously perpetuate itself into a state space that is both space and matter, and time would seemingly change entirely. Aspirations, wants, and needs, would instantaneously be realized by changing the laws of nature or time itself that govern this newly formed state space. It would be free-will taken to the maximum. No more anxiety, no more death, and life would be Utopian. People would be able to choose to live on their own Solaris, or join other people in a collectively created one.

I post this due to the deterministic nature of simulated realities, which in-of-itself would psychologically be so alienating and unfortunate. If such a thing could ever arise it would allow scientists to figure out if we really do live in a deterministic universe. Furthermore, what is perhaps the greatest thing about this sci-fi idea, is that you could create realities that are not constrained by the happenings of the world around them. They could technically be entirely localized.

What are your thoughts of living on this 'Solaris'?
