This is sincerely meant, but if you consider 2 and 1, isn't that a description of progressive taxation in the modern, regulated-capitalist, social-democratic welfare state?
(btw, I made that description up to try and describe the kinds of states I'm referring to. e.g. the USA once was in that category and no longer is in my view, while many European countries probably are in that category).
EDIT: I'd like to point out, I'm assuming no/little corruption. i.e. the theoretical view of such a state.
Not really; taxation is compulsory. If you steal everything I own and distribute it to try to improve other people's lives, I don't suddenly have any kind of charitable moral high ground because of where my money went, and neither would I be complicit if it were used to hire puppy hitmen or whatever evildoers like to do these days. The end effect is similar, but intent matters.
I agree that intent matters, but insofar as a state governs with the consent of a majority (leaving aside questions of whether that consent is real), then taxation (incl. the level of taxation and its distribution e.g. welfare vs warfare) represents a broadly agreed mechanism of the state to provide the kind of safety net that OP described as levels 2 and 1.
Personally, I live in such a state (not the US), that has a safety net, and am happy to contribute via taxation. Not all my fellow citizens are happy to contribute and I accept that. I earn a decent wage and don't jump through hoops to minimise my tax. At the end of the day, people vote for governments that are more or less taxing.
IMO then the people happy to contribute to such a system would mostly fall under 1/2 (under the assumption that one's motivations are altruistic and not centered on the communal benefits they also receive), but the people who aren't happy to contribute would not qualify (at least, not via their taxes alone -- there might be other reasons for rejecting taxes, and they might contribute elsewhere in a way that still puts them in the 1/2 category).
