To answer the opening questions, I have nothing of real importance to hold on to in my life and I don't see that changing in any conceivable future. After that, there's the comforting certainty of death that nullifies everything anyway. If I had to choose between this and a gamble that can result either in the same finality of a pretty meaningless life (in the grand scheme of things at least) or my perennial existence in cyberspace where I'm pretty much free to do whatever I want, I would be out of my mind to refuse. I would never look back to my past life as I have nothing to lose. I don't see why anyone should have a saying in this and decide in the place of an individual if he should do it or not. Of all conceivable things, at least the conscience that emerges from the stuff going around in your skull should be yours to do with as you please, without external interference. You may call it escapism, I call it a shot worth taking.
The topic itself is quite fascinating. The fact that your mind happens to be inhabiting a body is more or less "a by the way" that may not be exactly relevant in the long term. It's not that inconceivable to imagine a future where you abandon your husk, send your mind over at the speed of light to a different planet and just build a physical realization of yourself there, from dirt, with whatever adaptations you need to survive in the new environment. I believe that the "self" and its freedom to navigate streams of thoughts are the only truly enduring aspects of your being. The fact that your mind inhabits a body or a hard-drive means very little as long as it remains free to think.
If you are into reading books, I recommend an old little story that touches briefly, but beautifully, on this matter, "The Mysterious Stranger" by Mark Twain. If you are into video games, a title that is closer to the topic and brings some interesting questions is Soma.
