I mostly agree with what you're saying but that doesn't preclude some issues with the way globalization is implemented in practice. Take your example of the British Empire. Its arguably one of the foundations of the modern globalization process but its implementation led, in part, to the
Bengal Famine. So while globalization is a natural process with momentum behind it that does not mean in practice its being implemented with the best interests of the world's citizens in mind.
I don't think globalization as practiced now is going to lead to another tragedy like the Bengal Famine, in fact it could very well allow us to better respond to one, but the idea is that globalization is crafted by a small international economic elite and their collaborators in the political class for their benefit and I think there's some truth to that.
