There's a reason that dictatorial, authoritarian, tyrannical, despotic and oppressive are all synonyms of prescriptive. Prescriptive is forced upon you.
I don't really find those synonyms under prescriptive in thesaurus.com or MerriamWebster.
Most definitions I find are simply setting down rules or norms, sometimes with a connotation of being based on tradition. The others you list generally have an oppression element different from general rule or norm making.
