If you edit the Stylesheet ONLY all the rest remain as shipped. That is why list by files contained is a good alternate.

By changing some files (stylesheet, removing css from the xhtml, correct typos, getting smart quotes, etc) the CRC is no longer correct. As soon as this implemented, I am very sure that ADE will get an update that only verified epub's can be read. No longer manually created epub's.

I understand the problem posed and I would also not like if someone would hamper with my work and then make it available as mine. However, I do not think this is the solution. What is, I don't know. Perhaps if they make 'perfect' xhtml files and only generate the CRC on those files...

If Adobe were going to do that, they'd have done it already, restricting ADE to using ePubs containing Adobe's DRM.

Can Publisher sell DRM protected epub with their own site.

Yes (see Simon & Schuster). However, expect to pay Adobe a lot of money for the privilege.

And again, it is useless. DRM can be removed quicker than then it is placed upon the epub.

And I've had issues with S&S. Finding someone at S&S who could deal with the problem was a bitch. And the only solution I got was my money back and not a fixed copy of the eBook. Fortunately, I was able to strip the DRM and fix the problems. But most people won't be able to do that or know the first thing about what to do to try to find someone at S&S to actually deal with the problem. And refunding the money doesn't help in the fact that people would not be able to read that eBook. The problem I had to fix after the DRM was removed is that the CSS was a total nightmare. And it caused the eBook to not properly display with formatting. I had to really fix that up big time.

The bottom line on DRM:

It doesn't hurt the bad guys.

It doesn't help the good guys.

Quite true. But then the sentences wouldn't be parallel.

And then you have content that can not be read on a standard ePub or Kindle deviced

It can't prevent people with enough motivation and|or money, but a simple way to do that is to publish in print only, on quality paper, very good typesetting etc.
In other words: DRM is as easily removed as suits are convinced it's a solution to their perceived problem.

EDIT: One more thing. If you value not just the content of your publication but also care about its presentation, try to view a document you created on either ADE or a reader that's based on Adobe's RMSDK (there's no point in viewing a book that's been designed specifically for one reader, create a short booklet the way you want it to look).
