Bungie does not allow game sharing because they disapprove of two individuals sharing one game, yet those who abide by their rules and buy separate games are unable to play within the same household. My brother and I cannot play destiny while I'm home from college. He bought it two days prior to the patch. Bungie has responded to one forum post on this issue and has yet to discuss the steps they are taking to fix this. Most of the community is unaware of this issue and Bungie may keep it that way until it is fixed. I hope you decide against this decision and keep those in need of a fix in the light.
