Good questions!

To address your first one has anyone from the IF verified that the economic model is accurately described? No one said it to me directly, but Dom reposted this on his twitter on his own and a couple of IF members told me on discord "Luka nice post!" so I guess I got more or less everything right. This article doesn't contain any private information. It's publicly available and anyone who wants to do their own research can do it and I advise them to do it. Don't follow me blindly.

As for the second question about resources. That is a good question and I advise you to join Discord and ask all your concerns there.

As to my answer to that question after asking similar ones and doing my research.

Every node will prune transactions after some time. So only a limited amount of resources will be required by every node. UTXO that meet a certain threshold will be kept forever (dust protection). That doesn't mean you can't send 1 iota after coordicide. You can, but you'll have to clean up and combine those smaller UTXOs into a larger one or you may risk nodes deleting that UTXO and in fact "burning" your dust. Data transactions would also of course be pruned. Who needs those transaction can run a permanode or a selective permanode. Consensus nodes don't need to store them forever for you to verify that it's true. You could easily check the cryptographic proof (similar to a merkle tree) that leads from that transaction all the way to any recent transaction in recent history that all consensus nodes agree upon. If the cryptographic proof holds true you know that the data isn't tampered with.
