If you're arguing that it should be "taken" as an easement of necessity, that's separate, and a more political question.
Easements by necessity are granted generally when no other access is possible; they're not for convenience.
Additionally, (for private party transactions anyway) the party that creates the encumbrance is who is responsible for granting access. If you're not responsible for isolating the tract of land, then there's not (usually) any requirement to grant an easement. And even if there is, it wouldn't be a public easement.
And by responsible, I mean in terms of land transactions and changes in law, not putting up a gate.
The only reason this seems unusual is because a rich person is affected this time.
It's only unusual because when having a disagreement with the government, 99.99% of us can't afford to fight the government based on principle.
The Coastal Commission was established in 1972 to improve access. The act grandfathered in properties with no access, but requires any improvement or change to pull a permit with the Commission. The Commission requires public access when approving any permit.
