Yes, and that risk places a roadblock in the way and often dissuades people from killing themselves, forcing them to try to struggle on - and quite often, given time, they get better. Removing that obstacle by getting a company to do it, means that a lot more people are going to kill themselves, who would've gotten better otherwise.
It's not hard to find reliable suicide methods online (or at least it wasn't 25 years ago, ask me how I know) and as for a family member finding you...well, if you're willing to tell them that you're going to a clinic to be killed, or capable of arranging for them to be told, it wouldn't be that hard to make sure they didn't find you by scheduling a text to the authorities or a friend, to be sent after you're dead.
Really, it's not good enough to say "committing suicide is hard and scary, so we now need to pay companies to kill suicidal people."
That's so dystopian that it's wild.
