The russian were not forced. It was part of the Tilsitt agreement to have Russia snatch Finland away from Sweden.
To come back to the question of the thread, it is a mistake to think Napoleon's goal was to shut out all british commerce out of Europe.
Napoleon"s goal was to reach peace with Britain. His problem is that Britain never sincerely adhered to a peace where the Rhine, from Alsace to Zealand, would be the frontier of France.
For the British ruling elite, the peace of Amiens was just a temporary test, to which they agreed because the country faced serious trouble and needed time to rest and rebuild its forces. They endlessly set up coalitions on the continent to undermine the french position. And since Napoleon won these wars, well he had to take more guaranties on the continent to build a balance of powers even more favourable to his country. It was a fight to the death between the two most advanced nations of the world, a real new hundred years war (this time not between dynasties but really between nations), which had started in 1688 and ended in 1815. A fight in which the british did not want to make a deal.
In 1814/1815, France definitly lost and became a second class power in the world, mainly because it did not keep control of what would become major sources of industrial power in the 19th centyry : Belgium, Luxembourg and the Rhineland.
As far as commerce is concerned, the blocus was just a mean to force the british to accept a peace in which France widely dominated continental Europe. If ever the British had accepted peace after Tilsitt, because for example Napoleon had not overthrown the Bourbons of Spain and had not invaded Spain, then what is imaginable is a kind of selective protectionnisme, like the zollverein which was soon going to be set up in Germany.
Nobody had interest to be protectionnist against the exotic goods which the British imported from all over the world and sold back to european consumers. But many countries had interest in protecting their nascent industries from british competition. Remember it was a mercantilist world.
