I like this common definition: Freedom is to do whatever, whenever you like as long as you don't infringe on the freedoms of others.

When the infringement and how to fix it is open to debate, I'd rather not have the Sierra Club filing lawsuits as though it were the supreme arbitrator of justice.

As far as the individual versus the collective and planning vs the market, I think a good analogy would be cafeteria style dining in a cinderblock building as opposed to a nice, quiet, candle lit table with a choice of carefully prepared meals and a good spirit or two. With efficiency as the only consideration, choice is removed.
