> the means of production naturally belong to all humans collectively
I don't think anything "naturally" belongs to anyone. The whole notion of property and its ownership does not exist in nature - it's a social construct. So it's up to us to figure out the arrangement that works best, depending on our definition of "best". That is also inherently subjective - some people would claim that it's best for property rights to be absolute and inviolable, as a guarantee of stability, for example.
I think that long-term, some form of collective ownership is the only way to stabilize. But I don't know what form it would take. I doubt it would be anything similar to self-proclaimed socialist states of our age, which have clearly failed in that regard (indeed, many lefties argue that they don't actually have society-wide collective property ownership, but instead it's the collective ownership by the ruling bureaucratic elites - "the Party" etc - excluding your average citizen).
> being born entitles you to be kept alive by the rest of your species
We're clearly heading in this direction. In fact, I would even say that first world societies have already adopted this maxim in fullest, it's just not worded quite so bluntly. If you go around and ask people this exact question, many would probably say "no". But if you go around and ask the same people about specific policies like free healthcare, unemployment insurance, disability insurance, ER not allowed to turn people away etc, that all add up to the same thing, you'll find a lot of people in favor.
> resources should be allocated based on need
This follows from the previous point, with the caveat that the "need" here is not some arbitrary subjective desire, but what's deemed to be a real need by social consensus. What this consensus is, exactly, will likely evolve over time - today we mostly talk about food, shelter and healthcare, but we're already starting to discuss e.g. access to Internet as a basic right. The logical conclusion to that is something like what Bujold described in "Barrayar":
“Poor?” said Cordelia, bewildered. “No electricity? How can it be on the com network?”
“It’s not, of course,” answered Vorkosigan.
“Then how can anybody get their schooling?”
“They don’t.”
Cordelia stared. “I don’t understand. How do they get their jobs?”
“A few escape to the Service. The rest prey on each other, mostly.” Vorkosigan regarded her face uneasily. “Have you no poverty on Beta Colony?”
“Poverty? Well, some people have more money than others, of course, but . . . no comconsoles?”
Vorkosigan was diverted from his interrogation. “Is not owning a comconsole the lowest standard of living you can imagine?” he said in wonder.
“It’s the first article in the constitution. ‘Access to information shall not be abridged.’ ”
Thanks for answering despite the blunt wording. I think it makes for a more honest discussion, but it riles some people up to the point of derailing debate.
Curious: do you see these questions as anything more than questions about "what is consensus at this time?" Does it even make sense to seek an answer on a different level than an opinion poll?
In other words, can morality be more than popular opinion?
Absolutely. I don't mean to imply that one's individual morality is in any way subject to popular opinion. I'm talking mainly about popular opinion in this context, because that sets boundaries of what can be done politically (and remain stable long term). But, of course, there's still the moral imperative to influence that opinion in the direction that you consider more right and proper.
