Your premise is invalid to me.
I wouldn't tell a person with depression to "just be happy", but neither would I allow them to humour the idea of giving up on life.
They certainly won't find companionship by giving up and deciding to mess around with bots instead.
It's more like telling a depressed person to get some sunlight in the morning or whatever. Is it going to fix everything? No, but you do it anyway, because behaviour is sticky.
