Poor reasoning. It assumes the industry is just fine with analog being so easily copied. If analog could be restricted without being easily defeated it would be, and it's one reason digital was embraced because it can be. They don't want analog so easily copied but really have no good choice on that, and the industry also knows we are fast moving towards people expecting HD quality so in the not too distant future you will see less analog outputs. Just as people were forced to get a digital TV or get a (somewhat clunky) converter box, to watch OTA, so too will they have to get analog out. Cable companies too are fast moving towards new delivery systems that outdate simply watching by attaching a cable, among them Switched Digital Video and of course Clear QAM. After a period (I think a year) you will pay for use of those needed boxes. So your complete premise is very weak at best, there are very credible human beings that understand why Analog is tolerated to be easily copied, for now.
I disagree with most of your logic.
The primary, if not only, reason the TV was converted to digital was because of bandwidth and frequency allocation. Digital TV takes a fraction of the spectrum to transmit. Analog video is HUGE and that is why it was converted.
Additionally, the power required to transmit analog is huge in comparison to digital and using digital technology the data can be compressed to a mere fraction of the same data in an analog format. Either can be encrypted for security.
