Say the Six point movement is accepted
Would this 6 point hold over time
Would this enable Bangladesh to remain a part of Pakistan

There is a problem with the Six Points though, which is why I suspect it was rejected by West Pakistanis universally (including it seems West Pakistanis of the Awami League when the West Pakistani president of the
All Pakistan Awami League (as the league was then known) rejected it; it calls for a "true federation" of Pakistan but in essence envisions a very weak confederation of Pakistan. It doesn't envisage a central/federal government with it's own powers to raise money, but a "federal" government that is only "entitled" to a share of subunit revenue. Such an arrangement
will lead to friction from funding issues between the subunit governments and the "federal" government.
Additionally the Six Points clearly seems to envision two different customs territories (East Pakistan and West Pakistan) with free trade between them. Thus it means there is now way for the federal government to even raise revenue from customs duties if it were to be given that power because it would have zero control over customs. It also weakens one of the federal governments only two remaining powers because the subunits are envisioned as having power to to sign economic agreements with foreign countries......now even with the United States you have separate customs territories in the form of the 50 States + Puerto Rico as one customs territory and each of the remaining territories forming a separate customs territory
but the other territories have no power to sign separate trade agreements and trade agreements signed by the US apply to all US territories; so even if hypothetically the duty on say fish was different in the 50+PR as in American Samoa, the combination of free trade between the US and all its territories and application of trade agreements to them all means that if for example before a free trade agreement an exporter from Singapore had to pay $12 per tonne in duties on fish shipped to American Samoa but $5 per tonne on fish shipped to California then any fish shipped to American Samoa,
once cleared of duties there should ship freely to the US mainland and that once a free trade agreement is established then if it is meant to cover all US territories then the Singaporean exporter now pays $0 in American Samoa and in California.
It also envisions separate currencies, or at the very least a single currency but oddly enough " effective constitutional provisions should be introduced to stop the flight of capital from East to West Pakistan. Furthermore, a separate Banking Reserve should be established and separate fiscal and monetary policy be adopted for East Pakistan". This in essence means that either separate currencies are introduced without capital controls between East and West Pakistan
OR a "single" currency is established but with capital controls between East and West Pakistan (which means you can't really use money from West Pakistan in East Pakistan or vice versa and thus it is a single currency only in the fact that the banknotes and coins look the same, but you can't freely use them in the two parts of the country).
The plan itself was unworkable so long as the Six Point pioneers and advocates kept saying that they wanted it as a basis for a "federal" Pakistan. Because the actual points don't support that claim at all. Better they put forward plans for real democracy and a real federation or they simply abandon the idea of a federal Pakistan and call for an outright (weak) confederation of West Pakistan and East Pakistan.
