Hmm, Ashley those are good concerns!
I think I'm envisioning something more like with cigarettes, where there is really negative mandatory packaging alterations that explain everything bad about it. And then they get taxed (which is not quite 'silent' burdening, but more like negative publicity). That way it doesn't really come across as a good deed they are doing.
Also, I think the money doesn't so much need to go into infrastructure for water purification as infrastructure for access (more public water sources) and for education. The government could even use the money to subsidize water access projects in institutions and private venues (stadiums, arenas, theatres, etc). One of the big reasons people buy bottled water so often is not just their faith in it's quality, but it's convenience. If people could expect to find water stations more often wherever they went, they wouldn't see bottled water as so convenient any more. Water infrastructure is not cheap at all and I just think it would be a shame for the bottled water industry to get off so easily for taking advantage of a need in such an unsustainable way.
