Do you think its right that there are involuntary psychiatric holds for people who are only a danger to themselves?

One of the reason's why so many people don't admit to their therapist they are self harming, is because they fear being locked up in a psych ward, and the new restrictions on their life when they get discharged. Why isn't it a choice for the person to make if it's determined they're not going to be harming others?

Edit; Im not talking about Psychosis, or something like that, I'm talking about depression.
