You’re right that the Minchas Chinuch indeed understands Tosafos like you, but that still doesn’t answer my second point: that even if someone is ???? from ???? ??? by reason of not having ????, he can still bring it as a ????! (Besides for this being stated explicitly by the ??? ??? to ????? ?? ?”?, it is also clear from Sanhedrin 11a, where we say that Beis Din make a leap year if people from Bovel are coming to Eretz Yisroel but have not yet arrived; ??”? explains this means they are coming ????? ??????. Surely these Babylonians did not all own land in EY; yet they were still coming ????? ??????!)
