The right to run an oracle which broadcasts the winner of the SuperBowl is well protected by the 1st amendment.
The right to arbitrate a gambling contract based on the SuperBowl is not as clear.
However, there is plenty of cool things to like about a blockchain without POW. A blockchain is just a database which broadcasts signed transactions over a p2p network.
Forging a blockchain requires a validator to sign two conflicting transactions. When that happens, you have undeniable proof of fraud which you can take to a judge.
Compare this to most databases where a sysadmin changes a few values and deletes the logs, no one would be any wiser.

> On Monday, Mr. Thiel plans to defend his position in a speech and then a question-and-answer session with reporters at the National Press Club in Washington.
All they need to do is show two coflicting blocks signed by the "approver"
As for downloading the entire blockchain, light chain verification will make this unnecessary.

I think that until Vitalik pulls a Satoshi, Etheruem will never be as decentralized. This has pros and cons, especially with sharding/PoS around the corner.
Perhaps this is confusing enough to trick regulators, however I'm not so certain.
If the protocol developers and exchanges switch to a fork, there's very little the community can do.
Sticking with the former chain is difficult because 1) everyone else is calling a different chain "Ethereum" therefore you probably need to change your name to something else, 2) You need to be concerned with mining attacks
In my defense, I've spent a lot of time on /r/ethereum where a lot of people think that 51% of miners are capable of changing the protocol.
Could you elaborate on the issue, I take it you're referring to this
> In a proof-of-work blockchain, nobody rational would follow a fork with less than 50% of the mining power behind it because it would be vulnerable to attack by anonymous miners unless there were also a change in the hashing algorithm that required an investment in different kinds of hardware.
