Yes, if you scalp statues for any reason, you are committing an act which is morally bad, because scalping is morally bad. The ends do not justify the means. It is morally bad to make the decision to feed yourself or your family or raise money for medical treatment, or to fund charities by scalping, because it is always wrong to exploit other human beings regardless of the reason why you do so. There are people who rob convenience stores, banks, and who steal cars to feed their families, too, and again, no matter how noble the purpose, it doesn't make a bad act noble. There are lots of ways to make money without exploiting other people. On another note, poor people can't afford to have kids. It is morally wrong to bring children into the world that you cannot morally provide for, since to do so would be to guarantee the committing of wrong.
If the thing you want or have REQUIRES you to commit wrong then the thing you want or have must be wrong.
Again, I do not believe that one must commit wrong in order to feed one's family, unless one has had so many children that they have caused more demand for resources than what actually exists, in which case having too many children is the fundamental problem. This is rarely true, but I bring up this issue now so you won't feel the need to bring it up yourself. This way, I have already answered your question without us needing to post back and forth about that issue.
The rich dude you describe who has statues is neither morally good nor bad.
Taking advantage or other people is always wrong. That is the issue here. That is why scalping of any kind is wrong.
