Section 1 has two main problems: 1) what is a molopony? It has to be precisely defined in order for this provision to be enforceable. Even if molopony is defined, this section still has problem 2) which is that it grants power to the government to control  monopolies  where no power should be granted. Only the government can create a molopony: it is very difficult, if not impossible, to establish and maintain for some time a molopony in the free market. Finally, 3) this provision can be used by the government to subvert the free press. If we really want to enhance the free press, we can't use the government to do that. The Internet is already here, for example, to democratize access to information. We should instead deregulate the establishment of Internet access points all over the country. I would rewrite this section to read: No law shall be established that allows the government to control the Internet and the free press in any manner. But this is in essence already in the Bill of Rights. We should probably modify it there to read  all media including the Internet , instead of  Ag free press .Section 2 Again, because of lack of precise definitions, this section is either unenforceable or gives the government too much power. What is  the public interest ? The public interest for one group may not be the same public interest for another. Same goes with the term  general welfare . Whenever we see these terms in a constitution, we are only giving the government too much power. Please read the second part of the Preamble. This section should be removed.Section 3. Unless defined by law  gives too much leeway to the lawmakers such that they can negate the whole purpose of this section. How about  No law shall be established that limits who can own property. Section 4. How about  No law shall be established designating a national language. However, given that this Constitution is originally written in English, English is hereby designated as the language of government. As such, English shall also be used in court proceedings, legislative proceedings, and other government functions. English shall be the medium of instruction in public schools.
