Presumably California would look less kindly on someone saying to their lawyer, "I want to lock up this money forever", and the lawyer in response saying, "Yes, I will draft your will so that the money will only ever be spent in the manner you command."
In the current political climate I wonder if fee tail could be brought back. The predominate opinion among economists and, especially, legal scholars on the far right seems to be in favor of removing any and all limitations on the enforceability of contracts and trusts, and I could see the far right in many states embrace a return of fee tail as it would be easy sell to their political base as a way to preserve property in the family.
Unwinding capitalism as overly progressive and retreating to feudalism seems entirely in line with the politics of the present US ruling faction, and bringing back fee tail would be a natural step toward that.
