You haven't mentioned how public provision is to be made. I know that things like sanitation, energy, health, water, and so on can all be provided privately, by capitalists; I know that it doesn't work as well as public provision.
Here in the UK, all of those things were public, until they were privatised in the '80s. I'm in a position to compare the service we used to have with the one we have now. In every case, they're worse (I deliberately didn't mention telecoms). The only service here that hasn't yet been completely privatised yet is health; unfortunately it's rapidly being privatised, and becoming more like the US system (I've spent a fair bit of time recently in hospitals and clinics).
The NHS is paid for collectively; "free at the point of delivery", as they say (which is a lie). But they do refuse to do some expensive treatments; many other treatments have very long waiting lists (hip replacements). They only have to squeeze harder to force more people into private treatment.
