I think it should be an option for the terminally ill but nobody else.
There are people who are suicidal who don’t feel they deserve help and feel that assisted suicide is an option for them. We should not give them that option. Instead, we should spend that effort as a society helping them deal / get better.
I don't think this option is given to people who feel suicidal, so that's a moot point.
Also, people who find suicidal often will find a way, legal or illegal. This is about terminally ill people, and about not making things harder for them, or getting their loved ones in legal trouble.
