There's a bit of a trend lately around destroying transportation infrastructure to achieve vague goals. What is wrong with playing in parks?
I couldn't say whether public parks in Los Angeles are going away in general. I'd say "likely". But I think this article somewhat incorrectly frames how dire the situation is with respect to public parks in L.A..

And roads are transportation infrastructure, streets are to live on. That’s why the article talks about “reclaiming streets for civic live”.
