It's too expensive to be feasible.
Whether or not any creosote in the pine tar is harmful or not is up for debate. Creosote is a suspected carcinogen, but most of the creosote studies have been done using creosote from coal tar, not pine tar. It's a completely different substance.
There is suspicion that the whole 'creosote free' thing is a scare tactic started by a couple of people to drive customers to their product as opposed to someone elses. After all, people have been using Pine Tar from the feed store in soap for years, slathering it on themselves for skin conditions, using it for horses and dogs, etc. without a problem.
My grandfather (and a lot of other people) put pine tar on every wound he got (some quite nasty) and used horse liniment on sore muscles from the time he was a small boy. He died at age 97 when he slipped on the ice shoveling snow and hit his head. So take the 'creosote' thing with a grain of salt.
