They were completely sick of being pestered about it. There was clearly a reason they didn't reform after disbanding. Those guys had all kinds of personal relationship issues as people who had a long, complicated history. Furthermore, there was no way they could recapture the magic, as all four of them went in different musical directins.
John in fact was writing songs during that time - we have his demos to listen to from 1977 to 1980 -
Love you, Paul ❤
They were all asked that question ad nauseum.
