Is it too much?

I was thinking of how bands overload on gear. Is it too much? Some of the artists on this list are solo so that makes sense right? Maybe I'm just becoming a minimalist.

Animal Hospital-One man band with looping drums guitar strings etc...

Dosh-Sometimes accompanied by a friend but he is my favorite out of all the solo gear heads. His treated Rhodes sounds are great.

Hammock-Nashville Duo who I saw in store at Grimey's, cool sounds capes pretty boring live, and is it necessary to play a 5 different $2,000 guitars?

Last but not least-
BATTLES-I think they know how ridiculous they are, so it's OK. Tyondai Braxton solo work fits in well with the other pedal looper artists too.
