That is a possible scenario. There is still a moral issue, that of deception. If you're begging on the street for donations to fund a homeless shelter, those giving would likely be unpleasantly surprised to find the shelter uses the money to build luxury housing to additionally fund the shelter. Even if it is a solid strategy, you're still deceiving people to encourage them to donate.
