And btw, this is why I suggested to Zcash, they hedge their bets and also focus some of their efforts on the corporate applications of zk-snarks to privacy for public block chains with an optional viewkey for the government. This is absolutely needed by corporations if they are going to use block chain technology to interopt more efficiently. Zcash is sitting on a gold mine technology if they get some clarity into their strategy. I think perhaps they should have hired me. Any way, I am off on other project/work now.
That was the reason I started to support the Gadgetcoin developers, because they identified businesses need a private implementation of the blockchain, businesses simply can't operate with public blockchains. Such public blockchain exposes all their trading and transaction information to the public, which is simply not an option for business operations (now the GDC devs are unhappy with me because of my IOTA fight, but that is an other matter). I think you are quite right if you see there is a business case and your project can be successful in that area.
Let me add to both of your points, that the global government is also taking form but not entirely organized yet. For example, the G20 has just recently pledged to share information and work together on tax cheating. It takes a while to get all these 100+ nations to cooperate, but realize the leverage the G20 has over international banking (e.g. they threatened to shut off the Philippines' OFW remittances if the Philippines didn't comply with the wished for the USA such as ending the bank secrecy law in the Philippines) and over the internet trunk lines (undersea) and other geopolitical leverage.
It always amaze me how powerless we are when it comes to money, and how quick government and the money lobby can act. You remember, not long time ago the Greeks voted and said no to austerity. The vote was on a Sunday. The following week their prime minister sat down with the Troika and by Friday the prime minister implemented more severe measures that was declined by the voters just a few days before.
I think the Chinese, Europe and all others will implement those money control measures in a heartbeat when they feel the Status Quo needs to be defended.
