Your viewpoint seems spot on. However, what I think is missing from your analysis is the monetization. There is none of that at the base layer (after the reward window). Hence the data is idle in that sense.
It is up to the layer 2 for the monetization. It is also where the ownership will be tied.
The data is truly owned by nobody since it is public, yet can be pulled into an application and owned there. An odd twist but one that shows the exponentiality of the data.
Damn just got another article out of this. LOL
