Do you have experience with OBEs? I personally have limited experience. I'm no expert but I know a bit.

In my experience the kind of people who have the skills for engaging in out-of-body-experiences usually don't get a lot done. It rather increases akrasia then decreasing it. If you want to decrease akrasia associating more with your body is a better strategy than getting outside of it.

An even more powerful effect is present for social anxiety. Things like public speaking and rejection therapy are terrifying but by disconnecting my identity from my body, I would find that rejection is not as personal, just directed at this avatar that I control.

That effect is really there. You are making a trade. You lose empathy. Stopping to care about other people means that you can't have genuine relationships.

On the other hand rejections don't hurt as much and you can more easily put yourself into such a situation.
