Yeah an outrageous amount, plus ethical costs to undo all the fuckery, the lost peace, the labor and lost investments, and all of that doubled, is the correct fee.
If the house would have sold for 1m, ask for 50m, then the environmental damage costs in equipment and labor and plants and animals, so now we're up to 1b, doubled to 2b, and a fat 50% fuckyou fee on top and round up to 3b usd.
People need to aim higher. If the company won't pay and will ruin your life instead, then guess their intent is actual war, and they shall have it.
Don't let the bullies win. Fight back.
