ELI5: If singers can perform others' songs, why can't comedians use jokes from others?

With proper acknowledgement, like in the beginning of the act the comedian would explain there will be jokes from others, maybe even list the originator of the joke.
After all, I just want to be entertained, do I really care from whom the joke came from specially if I never heard it?

When a singer performs another person's song in public, or records and releases that recording to the public, the songwriter not only gets written credit but also gets payments over time at rates based upon the sales of that recording or performance.

When an honest comedian uses other comedian's jokes, the honest comedian has purchased the right to perform those jokes. Nearly every comedian has purchased jokes, and most will tell you where they came from if asked.

Most recent discussion has been about a female comedian who did not purchase the rights to some jokes, and then used them in a performance AND made money from that performance. That's the problem.
