Copying prevention:

-No, I dont like them!
-Yes, They might be effective on temporally preventing copying!

Although being temporally effective does not mean that their good will overdo their harm, or the cost of their implementation.

nowadays physical hardware locks may seem ridiculous but i think that digital and software ones will look as absurd in a few years(even now they are funny and annoying).

I dont know how much of the financial loss in software industries come from copying for personal use, but I think that the copyright enforcement should be directed towards copiers who do it for the purpose of sale and distribution. because I believe that with fair pricing and just licensing, even in the case of propriety softwares, people are willing to pay for their use.

and in the case of professional copying, this kind of copying preventions dont really work, because the mass copier already has or will develop the necessary skills to unlock any copy prevention, as they have done so far.
