There is no harm unless it becomes an addiction, knowing you shouldn't be doing it in the circumstances but do it, as Le Fusil reminds us. I know a few of those. I have less than 20 firearms, mostly shotguns, a few rifles and one pistol.  I'm not a collector although some non-shooters would disagree. I'll have no problems passing them on. I'm giving them away to family and friends while I'm alive as my parents did to their property and possessions to me and my siblings. "Makes no sense to keep them until we're dead," Mom and Dad said, "when you can use or sell them now as you please." Made sense to me. They died owning a little yellow Corolla. Their spirit made me what I am.
