I agree with your sentiment, but to answer your specific question comparing e-cigarettes to alcohol (or really Juul to Budweiser) - public acceptance. Alcohol, love it or hate it, is an integral component of human cultures going back millennia. Drugs (other than alcohol) are also important, but I would wager alcohol on its own is more important than all of the other recreational drugs combined (I welcome arguments against this unsubstantiated claim). People love to hate cigarettes, especially cigarette companies. Juul just got an enormous amount of money (almost 11 digits) from what was formerly Philip Morris. For the most part, attempts to regulate cigarettes have been successful. Hell, arguably attempts to regulate other drugs have been successful (the war on drugs is a mess, but outlawing psychadelics did impact their availability). Alcohol, on the other hand, is accepted by most people. Attempts to outlaw it have been less than successful (contrary to popular belief prohibition in the United States actually did decrease drinking, but it was still very unpopular). Taking alcohol away from Americans is like taking away our guns. Maybe it's for the best, but prepare for people to literally die fighting you. E-cigarettes however are still relatively nascent and could be banned before they'd be anything more than a footnote in human history.
