The convenience of it all.

As with most things in Japan you could get them out of vending machines now.

For just a few yen you could buy a temporary cloned body which in the comfort of your own home you could transfer your consciousness into it & do whatever you like to do in it.

Depending on the model you went for the body could last between 2 to 10 hours and could be put out with the rubbish for recycling which made living out your fantasies a hell of alot easier and a hell of a lot safer as you were always connected to your own body and could be transferred back at any moment which took the danger out of it.
