But to be displayed in MoMA she'd kind of have to be.

I guess I see your point, the fact that she is the widow is also part of the artist and the artwork. That's fair. But, I'll also say that who she is is the 90% part and the 10% is the art. If one anonymized her work, it would never have made it to those galleries or exhibits.
While I agree with you about Ono’s art, I disagree on this. I know art is subjective, but in my times at MoMA I’ve found it bimodal: works on display there either blow ls my mind or I just don’t feel anything about.
She was also well connected to that world (she was invited to join the Fluxus community and artists like Marcel Duchamp attended her NYC loft parties) and quite ambitious, so there's a non-zero chance she would have become even more prominent had The Beatles association never taken place.
I have no interest in that world myself, but to say she was a nobody without The Beatles simply isn't true, she was definitely a rising star. A household name? Probably not, but possibly. An artist from that period that could be exhibited at the major international galleries, have her works studied in art schools? Absolutely.
However I think she would have stayed relatively obscure had she not become "ultimate professional widow" as the article put it.
