Is benches for Supreme Court is a requirement?

It is quite obvious  that if the people who framed Constitution intended such a scheme, there would have been some 20 odd benches of Supreme court in all the States of Union instead of their respective High courts. The fundamental safeguard of justice is Hierarchy of courts. From courts of fact at the lower level to courts of fact and law and then Courts examining substantial questions of law alone. The contrary argument is as plausible, if one employs an analogy, that a company can have multiple Registered offices instead of branch offices for convenience across geographies. Or for that matter, stretching the argument logically, the Indian Parliament should have Sessions across the country to suit geographical expedience and satiation of regional sentiments. The Supreme court is the last resort of safeguarding fundamental rights and constitution and owes its existence to Constitution like a company does to Companies Act. As one cant  have multiple Registered offices without infringing a mere statute, contemplation of distributing Supreme court for popular convenience is against the Scheme of that fountainhead called Indian Constitution from which all laws emanate and are adjudicated under it by the Supreme court against the fleeting fickleness of populism. Interestingly though United Kingdom now has a Supreme court and it would be a such a mess if one wants U.S Supreme Court to have benches from Alaska to Utah. I wonder whether the Indian Law ministry needs a revamp instead of the other way round.Lastly it is the very concept of Geographical centralisation with the college of Justices from all parts of the country in a milieu far from local and regional considerations that had made Supreme Court what it is today. And by the way, a mere telegram from the remotest part of India to Chief Justice of India had paved way for important and land mark Public interest litigation affecting constitutional rights and continues to do so even today despite New Delhi being distant. Geographically speaking of course
