Being more serious for a minute though. The problem isn't that all of these laws are being put onto the statute book, it's that this clause allows the government to change/scrap any of those laws without requiring parliamentary approval.
If you were being charitable, you might argue that such is the bulk of regulations being brought in-house, it would impractical to labour parliament with such work, and that might be the case for such laws that require basic administrative changes in order to apply here. The problem is that it also gives the government the ability to change laws that are actually quite good and quite valuable, with no parliamentary oversight, and in doing so gives them power over one set of laws that they have over no other laws.
