You can't be "not convinced" that things would be better - "we" have a free market and that market produced sunscreen in the first place, without which we would have worse health outcomes. There's nothing to imagine - it happened. Things are better for us.
Not all things the free market produced actually have resulted in better health outcomes than if they had been disallowed (many result in the opposite, in fact) and certainly not better economic outcomes for the people who bought and used them. Regulation, as always, is a balancing act between enabling those who would do good and stymieing those (who with the best of intentions or outright sociopathy) would do harm.
So yes I remain unconvinced. Free market maximalists tend to highlight their favorite part of the story while ignoring history.
