The real value is probably in the fact that the non single use bags have actual value. As a result they're not thrown away so easily. IIRC the real reason for phasing out single use plastic is the pollution problem and us not having a good way of reusing the fibers as it's just not economically viable. For other fibers that is less of a problem. So, if you're replacing a single use plastic bag with a heavy duty plastic bag that gets thrown out after a small number of uses... Yeah that might be worse
