No it's not. It's a conscious minimalist choice. My booksmark bar in Chrome fits 18 links. There is more links than the websites I use daily or even monthly.

I think having more links than that it's HOARDING. You have the feeling of creating value by saving the links but in practice you won't use most of them and anyway you have history and search to help you out.

Chrome even remove the bookmark bar by default. You have to add it back. That is to say Bookmarks is for power users and the most powerful ones are probably just being collectionist rather than pragmatist.

You're just not a bookmark user. Many people are, and Chrome is a much worse browser for those people than, say, Firefox where you can display a persistent bookmarks column. I have a folder with a couple dozen bookmarks of webcomics I read. I have a bookmarks folder with studies and papers regarding points of contentious online discussion I can reference without relying on Google. I have a folder of blogs I enjoy. I have a folder of bookmarks for various projects I find interesting, and every couple of weekends I pick one and give it my best shot. I have a folder of reference pages and sales pages for my project car.

in practice you won't use most of them

No, you won't use most of them. Because you're not a bookmarks user.

Just checked and Chrome allows bookmarks allows for folders. You can create 18 folders in the bookmark bar and those can even have nested folders. I think that's a LOT of folders and a LOT of flexibility even if you need it.
