你以为印刷纸币能强多少吗？
纸币同样需要砍树，还需要特殊的印刷材料（我也不知道管那叫墨，还是什么）。纸币会变旧，还会改版，政府总是需要印刷纸币。
Do you think printing paper money doesn't waste resources?
Doesn't printing money waste resources?Paper money also need wood and special printing materials. And paper money will get older. Government always need to print paper money for a long time.
