I find with this issue a lot of people start out being opposed to anything that is being touted as environmentally friendly. It's an ideological opposition that people then work backwards from to justify.
I've seen the same thing when it comes to eliminating plastic bags.
People will oppose this, and then argue that cloth bags are unsanitary, that they have to wash them frequently or they'll get sick, and that use of resources makes them worse than plastic.
And here I have been using cloth bags going on a decade, have never felt the need to clean them, and have not gotten sick from them to the best of my knowledge.
This is one of those issues where people have, bizarrely, taken a viewpoint because it's where their "side" falls, and aren't interested in facts or logic.
