Yes, do not disagree with you on this, although as practically few scientific work these days are conducted by solo scientists, it is likely that she has collaborators who can present the work and at least the poster gets displayed in the conference that matters. Conference organisers need to create more spaces for young and ECRs to attend conferences. Most mid-career academics etc who are not presenting anything significant at a conference can stay home and pay for junior colleagues to attend them (wishful thinking!)
