Agree, we all have right to our thinking but also have right how personal thinking should be measured. Reading your post, I note that you validate Namaz based on Muslims history because it is coming from it. You also validate you’re thinking that Namaz derives its value from going out, meeting neighbors, remain clean, focusing on God, practice humbleness etc. But can these traits not be independent of whether one is Namazi or not?
You create question; should physical process and contents of Namaz come from history or from the dictates of God? There are also Traweeh which is globally performed more forcefully than obligatory Namaz. How that fits into your narrative, Is it words of God or is ordained by history.
Your last point - doing well (Namaz) is better than doing nothing. But you have been lambasting Mullahs and Moulvis like hell but never said good words about them for doing good than not doing good.
Please clear the confusion.
