As someone else pointed out it was a leftist agenda that created the plastic bags to begin with. Effectively this undoes a leftist agenda and if Congress acts appropriately it can be made to put American loggers and lumber mills back to work.
Can't argue with that, but it avoids the point of my post. While almost all leftist agendas have more downsides than upsides, it doesn't necessarily follow that they all need to be eradicated totally. The fact that it's leftists imposing the removal of plastic bags might also give one pause as to the real reason behind it - the erosion of our Freedoms comes to mind as the main reasoning behind nearly all their agendas.
