One could say it's wrong to have government surplus dollars when there is homelessness in any shape or form.

One could say Lottery commissions are wrong for granting huge prizes to single individuals and not redistributing the monies out to those who need it most.

One could say that, and one could find many other examples of things that are wrong with how money is used or how wealth is distributed to people.

But it's a prize, the abbot is a man. Let him enjoy his prize and see what he does with it. As long as he's not attached to his material thing it doesn't matter does it.
