Did you miss the comments about the difference in energy/environmental costs when it comes to processing paper/vs plastic? How about the increased bacterial infections with reusable bags (my wife has a number and we do a load of them in the washer every time she shops - more energy costs involved)? Then, the next question begging to be asked is, "How much freedom/convenience are you willing to abide by being compliant to a host of rules and regulations that make some folks feel the warm fuzzies (some of the effects are not malignant - perhaps you would see fewer discards), but which actually have more harmful side effects than many of the 'miracle medicines' being touted on TV these days?" Many of the left-wing infringements on our Freedom have come from laws that were touted as having good side effects, but they usually have one good side effect to a handful of bad ones.
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.
