If something is that important as human survivor like health or environment or alternative energy, and any country can print their own money as they like, how something can be out of reach because it is expensive?

Medical machines, Solar power sites and similar

Just print it and use it, don't wait, we will deal with debts later, it is artificial debt anyway, nobody owns nothing to anyone anymore, it is all virtual and there is no limit to when you need to pay back, and to who? What will happen if some country doesn't pay debt back? I guess nothing. Nobody will starve because of that.
