Yes, they do. Most of the damage to the Tenth has been done via the Commerce Clause. The court tried to stop them during FDR's administration, but a heavy handed Congress and Executive bent them to their will. Congress has been all too willing to continue in the vein ever since. I see no good to be had in removing what little restraint has been imposed on them so far.
As for the rest of it, I see a lot of question begging, and no direct answers to the questions I've asked. What is it you're after that can't be had by amendment, and why is it there seems to be absolutely no consideration being given to that option?
Your questions have been answered. The answers require you to have a working knowledge of the Constitution, and you don't. You don't even have basic conceptual knowledge.
There are many copies of the Constitution on the net. You need to find one and read it. Read the Fed Papers too.
Post #1 and the answers will make sense to you then.
