I must admit, I am partial to your perspective. People have been building successful businesses for centuries without any notion or discussion of "product market fit". What's more, all these observations are written in hindsight like there's some secret sauce you can learn.

But rather than ruminating at length on "PMF", I just prefer saying "if people ain't buying, change what you're selling".

On the other hand, I can see how it's conceptually more relevant to companies taking the route of "raise capital first, get exposure second and figure out profitability later".
