But we want the cucumber, and any leftover cucumber will decompose to nothing - it doesn't require any specialised waste processing. The 1kg of CO2 to grow and transport the cucumber is a spent cost, but half a teaspoon of gasoline for every single cucumber is an obscene environmental cost. The same argument applies to your steak - the environmental cost of the steak is irrelevant, because the steak is the product we want, and again, leftover steak disappears without trace in very short order. The issue is the packaging, which we don't want but hangs around for half a millenia if disposed of irresponsibly. The goal of this part of the initiative is to deal with that "last mile" problem of irresponsible waste processing, because we can't trust people to dispose of plastics properly. That will inevitably have a knock on effect on the rest of the supply chain, because now companies can't sell products which use single use plastics in that area, so they'll look at alternative ways of packaging their product. That might result in some products having shorter shelf lives, but those products don't require complex waste management practices - they just move to different levels of the food chain. The other environmental issues such as the transport cost are an entirely separate concern which aren't impacted by this move at all.
