Motzi Shem Ra CAN take away someone’s shem tov.(see thread title”motzi shem ra follows me like a cloud”).Meaning,the person is innocent.
Aside from that,yes,a shem tov is very valuable.
I don’t know if people who suffered terrible losses (ex.young child r”l,or terminal illness)would agree that aside from a shem ra there are no significant tzoros.It’s a bit general.
