yeah, but hashi was stated to have his chakra replenished by his use of mokuton as well (just like he doesn't need to eat, sleep or drink). and another thing to point out, is that if one uses the byaku too much (like, a shit ton of times) u can go temporarily blind, so its not just the ms. my guess is that the ms has one of those high-risk, high-reward type labels to them. know what I mean? the ms has literally more strain than other dojutsu, so its not something unique to it. there probably is a reason (but overuse, as much truth as it may be, sounds absorb, since no character [besides for lucky/cheater obito] has used enough times to even count as overuse) we haven't been told about. all the other eyes have some temporary damage, but later heal, while the ms doesn't, which is very fucking weird.
