I'd love to blame it on the gear, but I'm just someone that likes to experiment - so no matter the mount, I buy and sell and trade the various gear.
M43 might be a bit easier because of the price point on the lenses and bodies now. Unless you are going high end, most lenses can be found for $300 or less on the used market and that is from the big players like Adorama, BH, KEH and MPB. Private sellers can often be found for less.

I've come to realize though that every system has their place and I can love them all differently, but equally.
m43 = smallest system for good light use
Fuji = small system, but analog feel - gives me the most "pleasure" in the shooting experience and I love using the film simulations
Nikon = my work kit. When I am on the job or "absolutely, positively need to ensure the shot and best quality" kit.
