More expensive to make, transport and install (heavier), and metal degrades far more quickly than plastic. Cast Iron is used for sewage and rainwater because it's non stick but is actually fairly fragile compared to PVC or whatever the fuck they use now

Huh I would've figured metal would last a while, but I guess it rusts easily. Suprised they haven't engineered ways around that.
If your water has a high pH it will corrode your copper piping. My water pipes were so thin you could chew them.
I mean you could use stainless steel or use some kind of coated metal so there are technically non plastic solutions it comes down to cost
