However it probably wouldn't work for a profit seeking company in this case. Big Corp owns Web Corp, and Web Corp owns the site. Which company is operating the site? If it is Web Corp. So when Web Corp gets fined, you lose your site. This is a problem for a profit seeking company, because it lost its value. If Big Corp owned the site, and Web corp operated the site, you may be OK. Your accountancy costs just went through the roof though. Not sure about this law, but some compliance laws treat the group as one whole entity to stop this sort of thing.
Since this applies to laws in general, are you arguing that corporations are a farce? I may be inclined to agree.
Edit: answering your other point, the company could not have no assets, if it owns the site then it has the site as an asset. If it runs the site then it will have cash etc. Etc.
