>I understand that convenience has value, and I wouldn't personally even care about this if we had a working, efficient recycling infrastructure. As we don't, I do care. It's practically impossible to recycle plastics economically. The best we can manage at the moment is down-cycling them into low-grade, low-value plastic products. There's an argument to be made for standardised and washable glass bottles with a deposit scheme, although that's unlikely to be popular. If we're stuck with disposable containers, Tetra-pak cartons are probably better over the whole lifecycle, although the calculations are extremely complex and we don't fully understand the environmental cost of a plastic bottle.
