Google, restricts certain businesses from making posts. This does feel unfair to prevent certain businesses from functionality but this is done to policies help make sure published content, including text, photos, and videos, creates a positive experience for customers. This is a system-level restriction on Google's end, and it does not matter whether you post from either Social Marketing or directly from Google Business Profile itself.

Some Google Business Profile categories or types that are unable to post are as follows:

• Gun Shops
• Adult Entertainment
• Alcohol-related categories
  

This list isn't comprehensive as Google has not made a list of restricted categories public. Things like reviews are automatically processed to detect inappropriate content like fake reviews and spam. Google may take down reviews or content that is flagged in order to comply with their own internal policies or legal obligations.

If you are concerned that your content may violate Googles content policies, you can verify here.
