Very few people (if any) have any misconceptions about any of this. It's an issue of language, not knowledge, as I noted on page 1.
Insisting that everyone append "without screwing up the game in some other way that pissed me off" or "without spending more effort than I feel like it's worth" to the end of every "You can't do X in system Y" is, fundamentally, the only resolution to your OP.
Posters in general are unlikely to start doing this, but you can mentally append it yourself when you read the post.
