It's important to distinguish between rights- and incentive-based objections to redistribution and efficiency-based objections to government spending. The government as an organization of humans is very inefficient and wasteful at accomplishing actual tasks (e.g., building bridges), but it's actually very efficient at redistributing wealth through pure transfers (e.g., the administrative overhead of social security is negligible compared to the amount redistributed). Thus the best objections are grounded in bad incentive effects or property rights, not the inefficiency of government.
