Harmful relative to what? An ideal world where nobody drinks?
We've tried idealism via a prohibition and last I checked, that caused so much harm we went back to letting people have a drink.
A comparison of drugs vs no drugs ignores reality - we are not lab rats, we live within a society and a little vice lubricates the cogs of society. To deny that this is how it is, was and always will be is not helpful.
Your point regarding for-profit companies is valid - the likely solution to that is to control advertising so that it doesn't advertise drugs, as we have already successfully done with cigarettes.
The larger point is that there needs to be a balance of individual good vs collective. When society tips too heavily in the direction of collective, drugs/corruption/disobedience/crime will always be a 'problem' because there'll always be people who aren't interested in living to enable arbitrary collective goals somebody has decided everyone else ought to follow.
Long story short, it's a balancing act, maaan :)
