The police, the government, the intelligence agencies and so on are not abstract entities, they are composed by people at all levels, in a capitalist economy, with human biases and wishes. There are plenty of documented examples of abuse of this kind of access for fun and profit.
And besides those not-so-abstract entities, they have contractors from private companies and corporations that aren't abstract neither, but even in abstract mode are driven by profit, not respecting your privacy/security/economy.
