The problem with completely anonymous encrypted "speech"(assuming speech enables transactions) is it comes with some nasty side effects. Murder for hire, child porn, terrorism recruitment among others. Does any government have it right absolutely not.

But, to me those are the types of battles you would need to be willing to die for as well as your sons and daughters because your enemies are.

Why not treat anonymity as opt-in?

Not everyone is paranoid about government espionage, data mining, etc, but if you are, then you'll have to deal with the additional baggage that anonymity brings to the table.

how could you be sure the site/app wasn't a honeypot for government.

You can't, it is impossible to build a decentralized and distributed database which prevents access to bad actors.
