It's a bad take because Oda actually set Zoro up for various plotlines
If he had never included anything about the Shimotsuki clan, nor hinted at Zoro's lineage in the SBS, Vivre Cards, etc, nor given Zoro subplots with the people of Wano, and all of that stuff...then that would be a relatively valid take although it would not excuse Oda in the slightest
