I think that a lot of people do have a physical Ithaca, but I don't think that I do and I think that a lot of people do not. This depends on your values and the circumstances of your life. My Ithaca is in the Mental realm and this doesn't mean that you don't have to go back to it.
And if you find her poor, Ithaca has not deceived you. Wise as you have become, with so much experience, you must already have understood what these Ithacas mean.
