My point is that limiting plastic use (especially single-use plastic) is a win in my book even if it is ultimately done for the wrong reason. Thus it's not worth my time going out of my way to disprove specific research that still ultimately points out the need to curtail plastic use...
What benefits? Single use plastics have one purpose and one purpose only: allow for fossil fuel producers to dispose of the ethane byproduct that accumulates during extraction. They get paid for the disposal vs having to process it as waste themselves.
