I don't know of any punk music made after 2000, that's all emo in my book.
I don't know what you've listened to but this post makes me wonder if you have a shallow view of early punk.
I'll also add that the poor production quality of most of it was not an artistic choice. They were not given access to decent recording equipment because it cost money and they were not expected to have any commercial success. Basically an early prototype form of algorithmic control of the public's taste. Later it became a statement of being outside the system because of the history.
