In the long run all OTBE* people search for ways to make their lives easier and more enjoyable.  Banning plastic bags doesn’t make life easier and it doesn’t increase enjoyment. For the least organized people in society banning plastic bags, that used to be free, makes grocery shopping significantly more difficult as this picture shows:

A selfy of the difficulty of not having a bag for bananas and one other thing.

* Other Things Being Equal (a great acronym)

I don’t oppose you using recyclable bags.  I don’t even oppose you taxing single use bags in general.  But I do oppose you distorting the marketplace by banning one product over another.  It’s odd that the people who support a woman’s right to choose about abortion don’t want the same woman to have a right to chose her grocery bag.
