Until beachcomber boy misses a drug interaction and you drop dead. Then you can be taken to the mortician. Since he would probably also be unlicensed in your world, you'll probably be embalmed with Gatorade.
The free market can solve almost all problems, but insuring that people in crucial professions where a single mistake can be a disaster are "ready to solo" is not one of them. Getting rid of licensing for "libertarian" reasons is just as silly as requiring ever profession to be licensed.
And licensing boards: there's never any market distorting perversions going on in that body. Nope, no politics and no quotas that artificially limit the pool of licensed folks in order to affect wages
Are you also fond of the FDA on similar "protect me from making stupid and dangerous choices" grounds?
By the way, superb post in #154! Someone with a handy ping list (a list of the uplifting variety) should distribute that one. I'll remember this post when my mortician pumps me full of Propel...I wont give a damn.
