You speak of this as if space migration is going to be scalable.

The likely end result of orbital systems looks something like this: https://m.youtube.com/watch?v=LMbI6sk-62E

The thing about the that is that it's not high tech. It's an engineering problem not a science problem. A massive engineering solution I'll grant you. I'll also concede that there are going to be a lot of steps on between.

That is your answer? Some crazy science fiction colossal international space structure that will require all countries of humanity working together to build?

The future is going to be very mundane. Conventional reusable rockets are going to be enough. The fuel cost of a launch is orders of magnitude lower than the cost of whatever satellites you're bringing into orbit.
