But is it fair to pass the externalities onto someone else - you get your prosciutto and someone else gets the mess? That's doesn't seem right to me.

As opposed to an arbitrary tax discourage something I would whole-heartedly support that the cost of all products includes the cost of all externalities.

Maybe people on a budget should wait in the deli line for their prosciutto, or buy something cheaper.

Only fair is to ban non-degradable packaging altogether. Give companies a year or two of transitional period and then heavily fine companies not implementing the ban.
