The nice thing about physical land is that you can't discard atoms (in numbers big enough to matter), and we have a multi-millenium history of landownership being good for fostering multi-generational wealth. You can also do neat things with land like agriculture, and I don't see the opportunity to do something similar digitally, since there is always a subscription model, not ownership. Of course, governments and real estate law can change, but it does so much more slowly than digital "law," and the benefactors of the last regime often overlap heavily with the benefactors of a new regime.
IMO, any digital asset would have to have a healthy and growing market for at least a generation or two for people to start making the types of investments you see with real estate.
