From Wikipedia
In the past, lower grade white elephants were given as gifts to the king's friends and allies. The animals needed a great deal of care and, being sacred, could not be put to work, so were a great financial burden on the recipient; only the monarch and the very rich could afford them. According to one story, white elephants were sometimes given as a present to some enemy (often a lesser noble with whom the king was displeased). The unfortunate recipient, unable to make any profit from it, and obliged to take care of it, would suffer bankruptcy and ruin.
So the only correct answer is obviously to start a rebellion and overthrow the king.
