People think differently, as you are implying it is not morally right, some people will call it God's blessing and opportunity, especially if the founder is poor and suffering from poverty.
Here is another point of view for those who are religious. If you believe in God's plan, maybe his plan for some people are too be poor and coming across money, or in this case a paper wallet, is his way of testing your faith and honesty. Making it yours might not be what he envisioned for you. I will end my religious preaching now.
