If one wants to broadly define "flight time" as "compensation", then any time I get in the plane as a PIC with private certificated, I am getting "compensation". It might be out of my household checkbook, it might be out of my "toy checkbook", it might be out of the "cash under the mattress", it might be out of lots of different checkbooks, all owned by me.
If I want to dream about starting my own flying business, and have a fresh-inked private certificate, and I decide to start building time, then the money I am spending on my time building is "compensation" by the business I will be starting in 209 hours.
