„die Ablöse“ meaning

I just came across this word in my course book and got confused as I searched for translation and on DWDS for explanation.
“Liest man Blogs, Artikel und Berichte im Internet, selbstverständlich größtenteils gebührenfrei, so ist sogar von einer Ablöse des Kapitalismus die Rede- durch die sogenannte “Sharing-Economy”.
DeepL translation on the last part: “there’s even talk of capitalism being replaced by “Sharing-Economy”.
Here Ablöse is translated as “being replaced”
But in DWDS the only explanation for “die Ablöse” is: (süddeutsch) Tilgingssumme (für eine Schuld)
As well as I searched the word for contexts, it mostly comes up as “Der Käufer verplichtet such, die Ablöse zu zahlen” “Der Käufer hat den Ablösegegenstand besichtigt”, in this case I understand that with the explanation in DWDS
With the word “ablösen” as verb tho, it has the meaning of “to detach, separate”. But I thought as a noun-form verb, it should have been “das Ablösen” instead of “die Ablöse”??? Am I missing something here?
