I agree to an extent, though it depends on to what degree do you consider economy to be zero sum. Are the resources required to make everyone physically and mentally healthy finite or not? If they are finite and cannot be scaled to provide for everyone, then someone must be left out. In that case you could print money (or transfer it from billionaires) and come to a temporary state of affairs where everyone can afford wellbeing, but if the labour and resources that provide said wellbeing don't scale accordingly, it just results in inflation on that sector and soon enough someone will be left out again. Same reason why you can't solve housing shortage by just giving people more money so they can pay their rent.
