No need to abolish money, it would be enough to guarantee housing, food, education and healthcare to everyone. Just remove the conditions for people to be blackmailed/taken advantage of.
Regarding Italy:
We have social housing that is crippled by bureocracy and corruption, you have to wait years in line to get a flat, so I can't really say we guarantee that.
We guarantee education, but we couldn't guarantee the same (good) level of education to everyone yet. Also we don't guarantee post high school education. If you need to work because you're poor and you don't have time to pursue a degree, that's mostly your problem.
Food is not guaranteed either, although we have several monetary aids to partially reduce the issue.
Healthcare is guaranteed, and excluding waiting times that are a bit long, I can say that healthcare really worked well for us. Nothing is perfect, but nobody is left to die because of preventable disease. No matter how poor you are, you will be treated.
So I wouldn't say in Italy we ever experienced what I propose, just a tiny taste of it.
It's pretty hard to test that out, though, when one side of the political spectrum is so convinced it will happen that they devote a significant amount of political effort to making sure it happens, preventing us from ever finding out what a well-funded and run socialist experiment would look like in the US.
But it's false.
Vietnam works for example, it even handled covid much better than other turbo capitalist powers.
And every socialist experiment has been characterized by different approaches and circumstances.
Rather than a factual argument, it's more an uninformed generalization, that sounds too close to the propaganda we are pushed on by media/politicians.
Do you want a strong factual argument?
Despite their claims, not a single capitalist nation has managed to solve poverty. And they won't ever, because without poverty there can't be the hierarchy much needed to force people to behave like cogs into the capitalist machine.
