glad you liked it. I'm trying to find some more interesting questions by trolling blog posts and forums

I find the answers a little bit misleading. If a column is part of another index, FK or constraint, it just can't be dropped (without dropping / changing the index, FK / contraint before), since it throws an error message.

And dropping an index, FK / contraint is usually a metadata change too (rebuilding an index to remove the unwanted column is of course not an metadata operation).

God is real, unless declared integer.

You should not be assuming this is part of anything else. If the question doesn't list it, it's not part of the scenario. This is a simple look at what a metadata operation is for a large table. If the item isn't referenced by another object, meaning it's not part of an index or other structure, it can be dropped.
