This is an interesting idea, but I think a lot of us don't become busy by choice- there are some things that just can't, and shouldn't be, cut. I'm thinking about jobs that offer support, family responsibilities... it's very hard to cut these things off the list, in order to make yourself less busy. And I find when I am not busy for long, I start to get sluggish, or lose my sense of routine. Ultimately, it's probably more about finding that happy medium than anything else.
