There is a HUGE amount of things you can criticize about MAID specifically (and should) but honestly there are only a few reason why we shouldn't let the living dead go:

- it's a slippery slope

- they are young, they might revive (metaphorically speaking)

- you believe god will punish them with eternal suffering or something, but then a lot of religions are fine with monks willfully passing one "through meditation" in old age

To be clear I mean "in general". Wrt. MAID specifically e.g., a week seem .... very short ... enough for some short term depressive bout or mental leap of judgment to end your live. But then like I said there is a lot to criticize about MAID.

But granting the living dead peace is, I think, not the problem here.
