Yes, I do. First, most nodes won't need to keep the entire data set. Just the hashes of each block to have consensus that the database wasn't changed and history rewritten. If they want to view events much further in the past and/or in places they don't store the data set for, there'll be at least one website with the entire global data set running OpenStreetMap's global 3D map along with same hashes for verification.

If when you mention "privacy", you mean how the network deals with the data gathered from objects the nodes are detecting, read on (But if you aren't, see my next comment below). As regards the data the network gathers from objects the nodes are viewing, you'll have to throw away this veneration of privacy to grasp what this is really about; like esteeming the Divine Right of Kings, it's not going to work any more. We're fighting over the right to keep riding this precious dead horse while corporations and governments are riding over us in their AI ferrari's because they know that the ones who'll will win are those who privately control the most data to train their AI's to do, well... everything that a human can do and more. They don't care about your privacy. It's long gone and turned into glue. They just want you to think you still have it so the conjob, the sleight of hand can continue till one day we wake up and realize all our land is in the hands of the Conquistadors.

Grassland is a competition based on Game Theory^[1] --What strategy should you take considering the strategy of others? The strategy of players in Grassland's game is laid out for you. It's to gather as much data about human activities by pulling in data from cameras wherever they can place them or find them online by setting its calibration on the virtual 3D map, then feeding those frames into the current eon's AI model, hashing the output, signing it and broadcasting it into the network. The more hardware they can throw at the problem, the more proofs-of-work they're broadcasting, the more tokens they generate, gathering data about you and thousands of NPC's and essentially trading whatever currency their compute costs are denominated in into Grassland's coin, a fungible, cryptographic token backed by proof (of work) of the internal activations of an AI.

The data, the emergent property of all this greedy, self-interested and beautiful computation, is merely the exhaust from this engine. And it's freely disseminated to everyone not just because it stands as unassailable proof an AI performed a difficult computation on human behaviour and earned those coins but because it's important that everyone, especially NPC's, knows the truth about the world for science, democracy, health, justice and all rational decision making. An embargo on stupidity and ignorance in that node's corner of the world at least. Advantage must then come from helpful innovation not parasites rent seeking on people's data.
