Increasing the cost of something (through taxes) most definitely changes behavior. Just look at a how plastic bag taxes reduced usage or cigarette taxes. The purpose is not to stop plastic usage entirely, but to recognize the true cost of the usage by factoring in the harmful effects now rather than down the road. That make it a fair market, not an artificial one. I agree research and innovation is needed, and tax revenue could help pay for it.
