Sometimes it's necessary. There is a fine line between making bad decisions and lacking capacity. If someone clearly is not stable then a court order to take medication is important so they become stable and have sufficient mental capacity to advocate for their wishes. Maybe they do not want to live on the street after becoming stable. Some people might say that it takes away their freedom, but is the guy wandering around the park talking to himself, or the person with schizophrenia is living on the streets truly free in any meaningful sense? No. Some people will say it's a choice to live on the street but like I said there is a fine line between making bad decisions and lacking capacity. They are living on the streets because they are not competent and do not have their frontal lobes working, which is necessary to make good decisions and decide what you really want. They don't finish developing till 25, which is why teens don't make wise decisions and are under custody of their parents. And when someone proves themselves lacking capacity, we take away their rights such as the right to sign contracts, vote, etc. So the mentally ill really have no right to refuse.
