i'd say minato can or i assume he can, like most have been saying you cant just take the fact that some doesn't use something they cant. that under plays alot of life lessons right there im pretty sure once or twice some people here have gotten in to a fight they knew they could win but didn't want to, and i think the same applies for minato the circumstances where never met for a real "need" for it. besides doesn't each clone made take up a huge amount of chakra so its kind of a double bladed sword. before anyone rages naruto got his large chakra reserve from his mother's bloodline and kurama not minato he is just an way above average ninja with probably above average chakra reserves and is very skillful in how much chakra he actually inputs.
