3) Do not worship false gods.
7) Set up courts and bring offenders to justice.
To a follower of these laws, being monotheistic means that any god that differs in some significant way from the God of the Torah is a false god and the offending worshiper of that God is to be brought to justice. How can you conclude that the Torah is for all humanity?
You seem to have not understood what the author was saying.
Presumably "no conversion necessary" was to be understood within the context of " in order to make a relationship with God, participate in the Torah's vision of repairing the world, and 'get to heaven.'" and "...the Jewish idea is that the Torah of Moses is a truth for all humanity, whether Jewish or not. The Torah...presents seven mitzvot for non-Jews to observe. These seven laws are the pillars of human civilization, and are named the 'Seven Laws of Noah,' since all humans are descended from Noah."
Keep the above in mind and reread the following:
"Maimonides explains that any human being who faithfully observes these laws earns a proper place in heaven. So you see, the Torah is for all humanity, no conversion necessary."
Plus it seems that you've read too much into #7. Presumably the "Seven Laws of Noah" are also to be understood within the same context and would not necessarily be a part of the laws of the judicial system referred to in #7.
