For me it is simple, because we can't live without money. Do you know a proverb about money it says money is not the root of happiness, but without money is the root of sadness.But life is more important above all. So i choose my life without money because human has given by God a brain to be use. So i believe that humans can live without money.
It's simple for you because you're a simple man just as your thinking...
In todays' time, humans isn't capable of "living" without money, depends on what you consider living, is it just breathng and your heart beating or living as in living like a normal modern person should. If you were to live without money (that would include no social benefits and no begging) you'd probably die in a few months from some illness or cold, depending on where you live. Also, no social shelter would be allowed because technically u're using someone elses money to stay in closed warm place rather than outside. Humans can't live without money nowdays, biologically, if you were from the urban area born and raised, your organism isn't strong enough to handle the effects of the open without medicine for illness or food and shelter.
