You guys really do have a hard time thinking in context and principle don't you!
The reason that those particular tribes are mentioned are because they are the ones that the Lord is going to destroy totally. (Vs.2).
But in vs.4, it is stated why a Hebrew was not allowed to have any marriage with them-they would turn the Hebrews away from their own true God.
So, while the Moabite woman is not mentioned, the principle of why marriage to foreign women remains the same, their clinging to their false gods.
So, again, Ruth was a Mobite woman who converted and thus, could marry a Hebrew man and enter into the congregation of the Hebrews with full rights and privileges.
And I am still waiting for you to explain why Egyptian women were forbidden in Ezra 9:1 if the issue, for marrying foreign women, wasn't their clinging to their false gods.
Moabites ARE NOT mentioned because they are in their own category.
Deu 23:3 An Ammonite or Moabite shall not enter into the congregation of the LORD; even to their tenth generation shall they not enter into the congregation of the LORD forever:
Deu 23:4 Because they met you not with bread and with water in the way, when ye came forth out of Egypt; and because they hired against thee Balaam the son of Beor of Pethor of Mesopotamia, to curse thee.
The rest of your post is pure conjecture and speculation.

It very well could have been that for Egyptians. What's the point?
