Should there be a comma after "loose" in this sentence? [closed]

I read a sentence which was:

He reiterated his plea for a loose (united), confederation with considerable autonomy for the confederating units.

I don't think there should be a comma in between an adjective and the noun that it's qualifying. Am I right?

No, there should not be a comma between an adjective and the noun it is modifying.

He reiterated his plea for a loose confederation with considerable autonomy for the confederating units.

The inclusion of information within brackets does not make a difference as the use of parenthesis is to break from the rest of the sentence and then return to it.

You can sometimes use commas for parenthesis instead of brackets, but in this example, it would be confusing as it would look instead like you were trying to use a number of different adjectives and then included an extra comma.
