So you're saying if the music is good then the technique must be good...even if the technique is bad? There are lots of players making good music with bad technique. Often artistic talent and good technique go hand in hand but they are not the same thing.
I'd agree that sometimes if you want to sound like players who don't have great technique you have to play the way they do. But using inefficient or sloppy technique should be an informed choice to get a particular sound not because some guy on an internet forum led you to believe you didn't really have to think about it a whole lot much less actually do the work.
I'm saying if it sounds good and you're comfortable, that's more important. If you disagree. That's fine.
