I think it'd be cool to one day collect more crap with my kids or something, then pass it on to them in the future. Or you know, sell it all in a dire situation. Whatever comes first I guess 
Something tells me when I have kids, they wont be interested in "Dad's OLD games" lol
"Wanna play some Double Dragon with your old man son?" "No thats ok dad. Id rather play online with my friends"
And I certainly hope there never comes a time when I need to resort to selling my collection. Or I can consider the last few years a complete waste of time and alot of money and shoulda just stuck with good old emulators.
