Ok... so caffeine is addictive therefore potato chips are? Does not follow.
Addictive alone is not necessarily a problem, but it does mean there is the potential for companies to exploit that addiction to make money while causing great harm along the way.
> It's a free country.
A "free country" and regulated capitalism are not mutually exclusive. It's a free country and you need a license to drive a car. It's a free country and you can't sell someone baking soda disguised as flour. Regulations, done right, have the potential to make us all safer, and protect us from exploitation by capitalist interests. For example, stealing is very profitable... but we made it illegal in order to discourage corporations from forming around theft as a business model.
All that said, to be perfectly honest, my actual biggest beef with juul is the stupid disposable plastic pods. Everything else is... well, capitalism exploiting addiction for profit... at the cost of people's health. Which as you point out, is not exclusive to juul.
