I kinda fine with it. If I said I wasn't I'd be a hypocrite because so many of the artists that I love have ripped off or covered other peoples music before them. Led Zeppelin, Hendrix, Eric Clapton, The Who etc... I really haven't heard newer bands covering older songs because I literally just don't come across them. I stopped listening to the radio 10 years ago and I don't watch television anymore lol.
I can tell you, when I heard Metallica cover Turn the Page I wanted to vomit. I really hated that
Guns and Roses covering Knocking On Heavens Door is a good one, also Live and Let Die. I'm trying to think of more recent ones but I just can't come up with any.
Because I'm a bit younger than you, I'll be 42 in exactly 6 days, I didn't have a chance to see many of the artists I listen to, not in their prime anyway. I never got to see the Dead in 89 when they came to Orchard Park, I was only 11. Didn't get the chance to go to Toronto in 94 to see Pink Floyd. Page and Plant came here in the mid 90's, couldn't go. I like to see some tribute bands on occasion. Musical Box is a great cover band, seen a few Floyd cover bands, Grateful Dead cover bands. Those are all pretty cool.
TLDR: Yeah, I'm kind of OK with it.
