Eddard, I did read thru the thread .. for some odd reason, I am strangely attracted to the myriad of threads that pose the "where should I use my PV ..?? " ... question
The flaw in the logic (I'm assuming you are talking about the economic loss) .. is .. had the ability to smoke been hypothetically still available, and all other things being equal, how much business would have been driven away by smokers .. ??
Im not Eddard, but I have an opinion, so listen up.

.
All things considered equal?? As in zero excessive Gasoline taxes, zero excessive smoke taxes, zero ticket/snack bar gouging? No smoking bans? Ashtrays set outside doorways? Zero hate propaganda? Fear mongering replaced with honest integral education? Priceless.
The U.S.A. Would be rockin in prosperity. Especially with the bonus of the eCig, DIY, honest health education, ...
A soccer Mom would be able to control her rage as she transported the rowdy, noisy, kids in the van. She'd be calm, because...
1. It took $30.00 to fill the tank, instead of $80.00-100.00.
2. She can roll down the window and light one up if needed, to help calm & focus. (Hopefully an ecig of course)
3. She can afford to treat the team to ice creams or pizza and a MOVIE at the mall, after the game & still buy little Timmy a new pair of soccer shoes!
4. A carton of smokes for diehard hubby is $10.00 without the taxes, & she can still afford to get her hair done at her favorite salon.
5. Family vacations every year, with no worries about bans, or over priced gas. Priceless.
6. Seeing ANTZ panhandling on the streets instead of the avg marine? PRICELESS!!!!!
When the avg family is shelling out an avg of $1000.00 per month, to the excessive tax man, & big Pharma, there's not much left at the end of the money to distribute to the community.
PS. I'm not advocating smoking indoors, but I am advocating for freedom from persecution, freedom to stand outside OUT OF THE HAIL, freedom to vape stealthily indoors, freedom from excessive taxes, freedom from lies and fear mongering.
