This outcome was entirely avoidable, right from the beginning of development at Starbase -- and entirely predictable.
It's not even as if SpaceX doesn't already have a second Starship launch pad at Launch Complex 39A, at Kennedy Space Center. (Where they routinely launch rockets without environmental damage lawsuits, up to and including (historically) Saturn V and the Space Shuttle, which are the only vehicles of remotely comparable size to Starship.)
If they don't want lawsuits, they shouldn't have built a potentially explosive chemical plant on a space-constrained sites next to nature reserves full of protected species. Or should ship the Starship elements to KSC by barge for launch. Blaming the nature reserve and conservationists -- they were there first, before SpaceX moved in -- is a dick move.
