Curiosity, on the “indicated” issue, that was a quote from Chayei Moharan, written by Rabbi Nosson Sternhartz, who was the closest chasid to the Rebbe and served as his defacto successor (though Breslov gedolim have never used the title of rebbe). Rebbe Nachman must have known he was dying — his yarzheit is on 18 Tishrei, not very long after his last Rosh Hashana — and made it clear to Reb Nosson that he wanted people to visit his kever.
I see what you’re saying about tzedakah. But from the quotes I provided, it’s clear that Rebbe Nachman believed visiting him on Rosh Hashana would benefit the entire world. So it’s understandable to collect tzedakah. If I were in charge, however, I wouldn’t raise funds for Uman trips from non-Breslovers, because it might send the wrong message (that mystical pilgrimages are more important than helping the poor with their basic needs.)
One more thing about women. Rebbe Nachman asked, “Why don’t you make your wives Chasidistehs (chassidim)?”(Siach Sarfei Kodesh 2, 1-14). So he wanted women to follow his derech too.
