The difficult-to-collect facts would be those necessary for in-depth and investigative pieces. I specifically called that out above as being pay-worthy. I can absolutely see for-pay access to
those news pieces.
What doesn't work --can't work-- is charging for things like box scores, election results, stock news, press releases, traffic/crime/weather. (Excepting perhaps extremely time-sensitive subsets of that data.)
And if the NYTimes isn't discriminating between their quality, signature content and simple daily news - the customer isn't going to either. They're just going to be frustrated that if they try to use the NY Times for more than 1 big story a month, they're penalized. Or, god forbid, try to read the NYTimes.com at work, at the library or at a coffee shop...
