When I was in grade-school, my classmate's father was a collector of model trains. And he was, in fact, so avid and dedicated with his collection that every shelf and available space in his home was filled with those model trains. I indeed visited them a couple of times and, being the grandson of a railroader and owner/operator of a Lionel set myself, I was quite awed by the variety and cool stuff on display. In fact, his daughter once visited another friend's home, and she was utterly mystified as she looked around, asking "but where are the trains?"

Now there is surely a fine line between obsession and dedication in a collector's spirit, and this particular fellow became quite successful in real estate, so that he was able to open up a storefront in a very busy area of town and dedicate the space as his "private museum". By that time he had branched out into collecting automobiles, yes full-size ones, typewriters, purses (his wife liked those), phonographs and all sorts of other amazing, mostly mechanical, wonders. He took over for the local model train shop just down the way. So anyone in the market for a train set can also linger for a gander at his comprehensive museum setup.

So I am unsure if his obsession presented any sort of disability; he certainly ran a business, had a good wife and children (who also ran businesses), and he was eventually able to parlay this collection into something quite public, if only a breaking-even "vanity project" where his friends dropped by.

So, like, I would never discourage someone from cultivating a cool collection of stuff at home if there's a chance it turns into something like that. But just piling on ugly radioactive waste in your bedroom? I'm not sure that's a sane decision. I'm not sure that's something I would pay to see, or even come over for lunch. I would nod, smile, and call some hotline on the guy, myself.
