Did you even read the Koshiro flashback? The entire point of that scene was that young Zoro didn't understand Koshiro's mindset and wanted to brute force his way through obstacles by being able to 'cut anything'. Up until he met Mihawk, Zoro carried that unhealthy bull-in-a-china-shop mentality before realising that peak swordsmanship involves subtlety and being able to protect the things he wants to.
Before chapter 10001, Kinemon had arguably superior cutting technique to Zoro's, being able to cut fire and employ Ryuou against Kaido himself. His complete and utter defeat has shown definitively that swordsmanship is not about cutting technique any more than Luffy's road to the pirate king consists of how many blocks of kairoseki he can punch through. It's incredible how so many people can't interpret Oda's message about what swordsmanship is and is not.
