Nearly any other approach is more feasible to solving problems. If you are going to say such a thing, to be taken seriously you must articulate how you can re-align incentives to cause such a behavior change to happen at a large scale enough to move the needle. It’s not complicated. Tax the behaviors you want to discourage. Subsidize the behaviors you want to encourage. You can’t solve all problems that way, because of black markets and other “non-linear” effects, but in this case it is a perfectly reasonable approach.
