The reason why the people from the government as well as big investors are jumping in bitcoin is because of the new program that will stir and cause a revolution in bitcoin industry. That is the UASF a new kind of system in which the bitcoin holders and economic holders will have the power to dictate as to which change and code they will use to make bitcoin grow and develop. This time conflicting ideas of miners will be stopped and must comply to the wants and request of their clients.
On the whole I agree that the power should be taken from miners
Though I don't understand what makes you think that people from governments and big investors alike are jumping into bitcoin? The much hyped UASF hasn't yet been introduced but you already talk that big fish are going Bitcoin full scale. I guess the reality is far from that. It is not even certain that the UASF initiative will get accepted at all, let alone big investors going to pour their money into Bitcoin. If only just one big investor invested in Bitcoin any decent amount of dough, we would have already seen prices in many thousands by now
