Oh, Ueda joking about printing more paper currency? That's a classic! Because who doesn't love the idea of infinite money, right? I mean, why stop at printing a little bit more when you can just flood the market with an endless supply of paper bills? Just imagine the convenience of paying for your morning coffee with wheelbarrows full of cash. Plus, who needs trees anyway? We've got plenty of ink and paper to spare! But hey, in all seriousness, it's crucial to consider the potential consequences that excessive money printing can have on inflation and economic stability. So let's hope Ueda was just joking and not proposing a wild monetary experiment!
