You just restated the same thing without addressing the core similiarity.
If you consider the accident of birth in a certain country unfair. That is, Sven being born in Sweden and Sandeep in India which should be rectified by allowing Sandeep to move to Sweden (or Finland, or wherever), do you consider other instances of inheritance unfair?
For example, if Sven stands to inherit an apartment in Stockholm and a nice cabin in the woods, while Lucas' parents were renters who won't leave him much, should Sven's parents' estate be taxed at 100% to rectify this unfairness (or 50% to pass it to Lucas)? If not, why not? What is the principled objection?
It seems to me that both lines of arguments for inheritance (whether better capital allocation and stewardship, or simple blood ties) work just as well for material goods as they do for citizenship. And property is guaranteed by the threat of violence (often from the same actors) just like borders are.
