Abstract principles like "personal freedom" are incoherent and determine nothing. Suddenly, everything a person wants is "personal freedom" and everything they don't want is "personal oppression" or some shit.

It's just like the naive idea that the "non-aggression principle" determines how people should interact with each other. Suddenly every use of force that the speaker feels is justified is 'retaliatory' and every use of force they feel is unjustified is 'initiatory'.

The only coherence principles like this have are what people already commonly agree on. You don't need to base your politics on principles for that. They do not tell you how to harmonize ideological conflicts or develop and spread ideas that lack consensus.
