Let's just envisage what the future could look like when disposables get banned...
I'm gonna go for a presumably best case scenario -
Disposables are banned.
Flavours are not restricted too much, just the odd one like gummy bears (and bloo slushie!).
All the disposables on the shelves get replaced by the rechargeable, pre-filled-pod replaceable variant. They basically look exactly the same. The price is the same. Some disposable users even appreciate the change and get pods for them going forward (especially if there is an extra say 25% tax).
I'm trying to think of some positives here...
.. but you're still gonna get some that are just too damned lazy.. chuck them when they run out.. and just buy another (essentially treating them like disposables)...
FWIW, our disposables sales are at the lowest they've ever been since they took off (I think we sold just one today), but I presume they are still very popular in the convenience stores etc.
