The dangers to anyone near one of these if it explodes, especially to bystanders, some of which may be children, is too high for my liking. Thus I say 'ensure it is safe and then we can use it'.

A pressurized, homemade PVC tank is incredibly different from an industry designed and rated part made of polypropylene. I get that these are scary, and I even wouldn't oppose phasing out / banning the white tanks with the screw fittings, but a blanket ban on anything that reminds you of something dangerous you were once near is a bit extreme.

As an aside, I'm interested to see what wrapping these tanks in gaffers tape would do for their failure mode. Obviously the pieces would rip through it, but the added resistance right as they start to gain velocity may be of more help than you'd think.
