I don't feel like I have to justify my downloading of music, personally. It's pretty much legal here in Canada, or nobody cares. Either or.
Granted, I have bought pretty much all of CoB's discography (save for Something Wild), but that's not the point. The record store I have here is shit, and only sells the most mainstream music possible. For most of the bands I enjoy, The only two options I have for getting albums are... Ebay, or downloading. And I refuse to give my credit card number/pay money over the internet. Too easy to get screwed over.
Not to mention, I just don't have the money nowadays to devote a whole bunch of money to CDs; they've gotten way too expensive.... But that's not to say I don't jump on the chance at a CD if it's sitting there and I have the cash... I do try to support the band every chance I can.

But, back on topic, yes, I do enjoy Inearthed's demos. My favorite demo song would have to be Translucent Image, although the sound quality isn't that good. I wish the song had made it onto Something Wild, myself.
It'd be nice to at least hear the remastered version though, methinks.
