PVC is used in water pipes, bottles, packaging films, blister packs, cling wraps, and seals on metal lids.[2]

This is the most relevant one IMO. You can buy glass cups and jars, it doesn't matter if the water you put into them comes through PVC pipes! Even if you buy BPA-free phthalate-free bottled water, I think it's safe to assume that at one point that water went through several meters of PVC pipes to get to that bottle!
PVC water pipes must be ubiquitous nowadays, and are certainly better than the older copper alternative, which in turn is better than the older lead alternative!
Maybe the next step is special PVC for water piping. Until then I guess we're better than we have ever been, water piping-wise.
The most common water pipe in new construction is cross linked polyethylene. XLPE. It is stable, inert, and contains no plasticizers. PVC is often used for sewage drain pipes. Like the parent said it is the rigid crystalline kind typically containing minimal plasticizers tightly bound within the crystal matrix.
Home 3D printing fortunately uses mostly PLA, which is biodegradable. Though I'm unsure how degradable it'd be inside your lungs.
