In the full NY Post article, she says she got a quote to put a chain link fence around the property, but it would cost $50,000.
Sorry to belabor tbis. I think she wants the fence costs to seem unaffordable, as part of a media strategy to force the City to lure the squatters away with “kindness” (free housing, food, healthcare, services, etc.). The City knows that would end up attracting more “vagabonds” from far and wide, wrecking property values, causing huge public expense, and property tax hikes to pay for it all.
If chain link fencing costs $50,000, T-posts with 2 strands of barbed wire might be a tenth of that, and could define her property line sufficiently to eliminate one of the city’s excuses for not arresting/evicting the trespassers. She does not appear to want to solve her trespassing/squatting problem via eviction.
