Bingo.
I recall that when the cassette tape came along, there was a contemplation of banning it. But it was decided to be "undemocratic" to do so, especially as to uphold such a ban one would have to basically police very home.
Given that this was while the cold war was still going, the nations of the west had a low water mark to compare themselves to.
So instead home copying of audio was given a pass, as long as it was done among family and friends.
These days however you may not have a cop but you have a potential snitch, the PC. And with the USSR gone, there is no longer a low water mark to avoid being compared to.
Thus politicians today are all too willing to entertain ideas that just a few decades ago was unthinkable.
Never mind that copyright as a concept came about when the printing press was something manually operated, and was a law about profit sharing between author and printer (the latter likely holding all the cards, being the owner of a press and all).
That press was big, expensive, and needed to be operated for profits basically.
And the same held true for early music records and movies, both needed heavy an potentially manual machines to produce.
Now however you can compress all those machines into something that fits on a desk, or perhaps even in a lap or pocket.
That shifts things around in a massive way, and the need to have a profit motive to own and operate a "press" is gone.
