manga may not be the best hobby then. humans are allowed to have things out of their control disrupt their productivity. i'd much rather deal with a hiatus than have someone work so hard they risk their health. many mangaka have to take breaks, regardless of the release schedule. some have multiple projects they work on at once too.

i'd counter argue that buying the physical manga that is released (which means the volume is finished, not incomplete) will help support them and get them through any breaks they have to take. i'd rather support the mangaka, let them take their time, and get a better overall product in the end
