TPTB's premise is that IP addresses and other metadata are being spied on. You can't transact in basecoins, even just to move from one mixer to another, without encountering that exposure.
My point is (especially for corporations) all their proprietary data privacy is done in zerocoins and then balances combined into basecoins to cash out of the mixer, which doesn't reveal anything but the agggregate value of the private data that is in the zerocoins. That is a distinct and epic advantage over Cryptonote/RingCT.
Now you're on to this corporate blockchain thing which is probably okay if you are looking for a short term payoff (but you better hurry, as that iron is hot right now).
However, it is largely irrelevant to the question of decentralized cryptocurrency and certainly to Zcash, the cryptocurrency that is being launched (though maybe not the company launching it, as they could potentially get some business building blockchain applications for businesses, as Blockstream an others seem to be doing).
As for you giving me career and financial advice, I'll not comment beyond this non-comment comment.
Anyway, if you want to build other applications based on the technology behind Zcash (the OP asked this), you can ignore Zcash (which is otherwise a rather uninteresting Bitcoin fork) and focus on libsnark.
