So we have a false implication. You are asserting that your premise is true. However, you will accept anything (true or false) as justifying (implying) your assertion. That means logically the relationship between the two (the implication) is necessarily incorrect.
I'm afraid you don't know what it is to define a formal system. It has nothing to do of true or false which are always relative things depending of the formal system you define (paradigm).
You should read
Gödel's incompleteness theoremsTo define a paradigm such as "The only Universal and Fundamental value of all economic system is individual human being", it is not a question of true or false. It's a question of defining a paradigm, a formal system in which you can developp what is true and what is false into that system knowing that in all formal system they are things true you cannot demonstrate (Gödel).
If you need to exchange about economics on other paradigm, it's not what I'm explaining, it's not what I discuss about, It's not what about I exchange with. You can create another discussion on the paradigm you want, define it, apply it and follow it if you think it will give good results, do it, learn about the results, change it if it's not good, keep it if it's good.
