Besides, if the will of the people is to take care of everyone through social services, then why do you need a government to do it? It should just happen naturally. What you are saying, is that a few select people that are chosen by a popularity contest should be given the authority to make people do things against their will.
The question is - cui bono?
Your alternative presumably is the current system, where a few self-selected people, kept in power exclusively by wealth, caste, and social connections - often in defiance of real wisdom or foresight - force everyone else to act in ways that benefit that self-sustaining governing class at the expense of everyone else.
If you want to pool resources collectively in a smaller scale you are just replicating this structure with different powerful people, or different structure of power, but a society will always need it, doesn't matter if resources are money, materials or labour.
Yes, but that's a direct consequence of having an ill-informed, poorly educated , credulous, angry, compliant majority. Societies where the elite are looking to retain their power base will typically channel fewer resources to public education, and more to the institutions that reinforce their own position.
Difficult to undo once it's been started, and (IMO) it's been happening for a very long time in AU, UK, US -- and presumably almost everywhere else that self-identifies as a capitalist democracy.
So, yes, the will of the people can get hairy, but of the two options -- force the agenda of the elite upon everyone else, or work towards a better society -- the preferable option very much depends which of those groups you're in right now.
Also noting that if you're in the uninformed group, you may not recognise that, or think anything needs changing.
For me, I'd say that society is about taking care of everyone -- government should merely (!) play the role of the administrator in that process.
I always feel that way too many people I speak to think that 'the government' is some kind of independent force, rather than a reflection of what society wants. (Sure, in many cases, it really is a reflection of what a tiny handful of people orchestrate -- but since we're talking idealism here...)
