I don't know how people collect amps and cabs. Pedals are easy; almost too easy. They are small and relatively cheap. Basses run the gamut price wise, but don't take up that much space. Cabs are almost by necessity big, and amps can be, as well as being fairly expensive. If I had a finished garage or basement, that would be one thing, but my den is only the size of a moderate bedroom. It has to fit my music gear, computer\recording gear, books, and CDs. My wife doesn't want to see any of that stuff; so it goes in the den. I pretty much live in one room.
