That sounds good but it is not true. The distribution of income is not uniform on the face of Earth and that is not due to sheer choice. The places where people with lower incomes live are not always the places where they would prefer to live.
Location still matters for many reasons, infrastructure, safety, public health, climate, and industry-specific agglomeration effects being among them.
None of those are culture or intellectual pursuits all of those are local societal issues. I thought the question was regarding cultural developmet. Renaissance type things not code of Hamarabi type things.
Florence was a financial and trading center of Europe during the Renaissance when Thomas Cromwell travelled there. That economic power and probably that cosmopolitan atmosphere were what lay the ground for cultural development, specifically for the resurgence in arts and in scientific thinking.
Even with the internet we see that artistic and scientific output is uneven across the world. There are places where ideas thrive more than in others. For example, if you contribute to the research frontier in physics, chemistry, or computer science, you are very likely to be located in one of the few centers of thinking in your field.
I don’t see anything that obviates the internet as the leading cultural development exchange of our time. These centers use to be located along trade routes. This is no longer the case. Any group of people can gather anywhere in the world and create whatever.
