Marvel Comics' model of business is completely different. The company owns the characters and they sell new stories every week, as they have been doing for decades now.
A kid can become a Harry Potter fan, buy the 7 novels and get the complete and consistent story of the character growing up.
With Spider-Man, it's nigh-on impossible for a new fan to read the entire saga of Peter Parker's life. Even if Marvel finished its Amazing Spider-Man Epic Collection book series and kept it all in print, the reader would miss out on important developments and new character introductions that happened in Spectacular Spider-Man, Web of Spider-Man and Marvel Team-Up. Even if Marvel made every Spider-Man comic available digitally, they'd need a thorough reading order guide... and that would be tricky because issues of Amazing/Spectacular often didn't slot in neatly between each other, there was a lot of continuity overlap, sometimes even contradictions. Then there's all the changes in tone and language and setting and art style to contend with, not to mention the retcons, dated real world events, abandoned plot threads and sudden changes in charcterisations. Imagine if the first Hunger Games book was written by Stan Lee and the last was written by Nick Spencer.
So Marvel isn't really in the business of selling readers a complete saga with a beginning, middle and end. They're in the business of selling:
A. Their current product.
B. A curated selection of perennials from the back catalogue.
The current product needs to always stay appealing to the demographic they're targeting, to the newcomers and future generations. They can't count on everyone going back to read decades old comics in order to appreciate what's being done in the current product. The current product has to stand on its own.
