Now imagine a digital country. What’s the fundamental difference? You’re still interacting with an entity that is far away.
If an organization arose that provided benefits to members in a way similar to actual citizenships, it would likely be competitive and desirable. If this digital country managed to make itself valuable to established states, whether through money, talent, or otherwise, I see no reason why it couldn’t thrive and be comparable to tiny island nations like Vanuatu.
