> giving people the ability to voluntarily give "viewing keys" to law enforcement that prove which transactions they actually send/received
That's not a good thing.
The fifth amendment becomes weaker over time; and may not apply in locales outside the US.
LE can easily coerce you to reveal your viewing keys, and assume you are guilty if you don't. That would be a bug, not a feature. See recent discussion proposing that google make its expired DKIM keys publicly available.

Viewing keys are standard in privacy-preserving cryptocurrencies, and are required for payment detection without spend authority. CryptoNote derivatives like Monero also have them. We absolutely need to fight against misuse of this feature.
