What an oddball question! Why is modern day Israel subject to any type of religious commandment???
That would equate to every Christian nation, all of Europe and all of the Americas being (abusers of the "Law" of the Bible and not following the commandments of God - (from question)) today because they all charge usury, have immigration policies, have found corruption among their political and business institutions, have militaries to defend themselves, have imposed policies that are self serving and create greater winners out of them than their neighbors, etc.
Do each of us think and believe we are "right just because"??? I think so...it is called self-preservation and is necessary to maintain life.
