Of course it is, no argument there. The learning part works for me, too. But at least to me consumerism is not the same as GAS, and vice versa. To me consumerism is the kind of "shopping is a feeling" attitude and behaviour. Shopping for the sake of shopping, whereas GAS is something different, the urge to get a newer, better tool we want and sometimes even need to do what we do, even though not having one right now wouldn't kill us. 
I for one will openly admit that GAS did have a small part in my buying a BMPCC, along with those four or other somewhat similar reasons. That's why I added the fifth reason in that list. It's as much an edited list for myself, as it was a friendly pun towards you. I think it's quite healthy not to take ourselves too seriously all the time.
 
GAS aside, I don't regret getting the damn thing. The only thing I sort of regret is rushing to buy the cheaper LCDF loupe for it instead of waiting for the pricier Zacuto loupe. Only because the cheaper loupe was available immediately, and the Zacuto wasn't.  The price difference was significant, but not critical.
 
I actually like the simplicity of the camera, along with the 10-bit 422 ProRes HQ it delivers as default. The two major things I don't like too much is the quality of the lcd screen and the structure of the settings menu. There should be better shortcuts for some settings and functions. I wish it had better battery life and built in ND filters, too, but one can't have everything in such a small package, for such a price. Now I just wish I had more time and opportunities to play with it. This fall has been a bit of a disappointment, in many ways. 

I own a BMPCC and a GH2.  I rent other cameras for gigs... C100, C100 mk2 and most recently GH4.  All of the work I rent those for is corporate style paid gigs.  I have some strong opinions on the BMPCC.  It really is a love/dislike sort of relationship.  
When I began freelancing (after 12 years of being a media producer for corporations) I needed a camera.  I bought a Sony Nex5n. Soon after, I replaced it with a GH2.  (The overheating drove me mad on corporate gigs).  My next camera purchase was the BMPCC.  For months, it sat on the shelf - only getting used in one project.  That project was a short film which I was producing on my own time.  I didn't have to fit my shooting into a 2 - 4 hour window, like with many corporate clients.  And this is precisely why it sat on the shelf - It was a pain in the butt to use for corporate work.  1. The LCD screen isn't great.  2. The crop factor is crazy!  3. Battery life... not fun.
So now, it sits in my bag on every corporate gig still.  BUT!!! I have a couple short films in the works and I will certainly go for the BMPCC.  The image is LOVELY.  I purchased the speed-booster (just factor this into your cost - you want it.)  I also bought the Sigma 18-35 and a 50mm 1.8.  You may also want an EVF.  I bought a 5" LCD, but think I'll get an EVF at some point.  You also need shoulder rig at least...
The GH4 is really nice to use.  It sits in the hand really well.  The image is nice - but I really wish the image was more like a C100.  It's not as detailed to my eye and the color science isn't quite as nice.  But, it'll probably be my next camera purchase.  For the money - its really great and the ability to crop in on the 4k image is good to have.  BUT - I still would use the BMPCC for narrative work.  And I mean - every time!  (unless I needed a slow motion shot)
So basically - in my experience Blackmagic is for narrative work where you have time to set up shots.  The others (GH4 and similar) are for quicker turn around, run and gun, corporate work etc. Most corporate clients think DSLR footage looks just fine.  But, in storytelling - the feel of the image really can add to the overall piece.  And I would rather spend the time to have the image that I really love.
That's just my experience... hope it helps.
