That's true. On the other hand, out culture was for far more decades (nay, millennia) to the point that people could not care less about such accusations, and the power figures could do whatever they liked...
Also, it wasn't just an accusation in the "court of opinion", but a deposition to an actual court.
"In a deposition, Giuffre, née Roberts, claimed she was trafficked to MIT professor Marvin Minsky, who died in 2016 at age 88, as well as former Maine Sen. George Mitchell, ex-New Mexico Gov. Bill Richardson and money manager Glenn Dubin, whose wife, Eva, is an ex-girlfriend of Epstein’s."
Still, it's not proven and I'm against the "court of public opinion", at least in more shallow cases (e.g. Woody Allen). But here it's at Weinstein and worse level.
I can see some fake-victim badmouthing a powerful figure to bring them down. Or to blackmail them. Or for revenge (e.g. from a bad relationship, etc). So I'd understand it if e.g. it was fake accusation just against one person.
But it seems too much for a fake-victim to name names of several people, and powerful people at that, on top.
