If Myroria would prefer to stick with the longer form -- it seems odd to just legislate a single sentence -- here's a suggestion for the first clause:
"1. The government of Taijitu, when acting in an official capacity, will not recognize any noble house or any title therefrom derived, foreign or otherwise."
A suggestion for a fourth clause:
"4. Citizens and foreign residents are encouraged, but not required, to avoid personal use of noble names or titles in Taijitu, as a demonstration of respect for the egalitarian principles of the Glorious Revolution."
