I'm not really sure what would be considered cheap vs valuable here so I don't have a great answer there. My point was only that individusl data is collected and sold often, it must be valuable or there wouldn't be a market.
I'd be curious to see how the price compares when selling 10k individuals' data versus aggregate data the 10k people. Presumably if it was cheaper to buy all the individual data I would do that and aggregate it myself.
