People could live in the Virtual World just like living in a real life. The main difference was the fact that they still had to actually get out of the Virtual World because their lives were only sustained by the nutrient solution.
It was not very healthy for them to stay in the Virtual World forever.
The nutrient solution would only help them sustain their lives but many things still needed them to do it themselves. Such as exercising their body and many others.
Thus, even if they were very comfortable to live in the Virtual World, they would not stay there forever and only for a short period of time.
Some people even used the Virtual World to make their living.
There was no restriction for this, but there were also various documents that had to be filled if one truly wanted to live by working in this virtual world. After all, it still had to have legal effect for them to be able to open business or something like that.
