(some bits snipped)
1) Let's agree that what our wiki says in leisure=park defines what we mean by "a park is a park, like this, even if it doesn't seem like that is what other parks look like, exactly." In other words, what OSM says is a "park" is a short definition, but it is an elastic one which encompasses a big and generous solution space to include parks.
Currently the wiki page https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dpark defines an OSM "leisure=park" using a few words, and illustrates it with a picture of part of Central Park in New York. It then goes on to say that "leisure=park" shouldn't be used for national parks. It uses Yosemite at http://www.openstreetmap.org/#map=10/37.8230/-119.5060 as an example national park ( http://www.openstreetmap.org/relation/1643367 for info ).
I'd suggest that the state and county parks in CA such as for example Joseph D Grant https://www.openstreetmap.org/relation/3003169 are less like Central Park than they are like Yosemite. They might not be close enough to warrant a "boundary=national_park" tag, and some other tag (some sort of protected_area?) might be more appropriate, but they're definitely not an OSM "leisure=park" in a "does it quack like a duck" sense as per https://wiki.openstreetmap.org/wiki/Duck_tagging. On Joseph D Grant someone has added a "park:type=county_park" tag to try and help data consumers distinguish it from other "leisure=park"s, but that doesn't really say anything about what it's like, just who looks after it.
2) Landuse is not landcover and vice versa.
Indeed (and OSM is confusing about how it tags both of those) but that's not really relevant to the current discussion. Bits of a state park may be covered with trees, and some of those trees might be primarily there for future logging (or not) but that is a separate issue to the legal status of the state park and who owns and operates the land. There may be rules about uses that people can't use the land in a state or national park for, but that's normally different what it is currently used for. OSM has tags that start "landuse=", "natural=" and to a lesser extent "landcover=", but those landuse tags aren't just about land use and not all "natural" things are truly natural.
