What usually happens is I'll be browsing and find an article/code library/inspiring web design/useful tool that I know I can make use of later in some way, but if I just bookmark it then I'll probably forget it's in there.
I have very organised bookmarks but these only work for sites I visit often and I do use tools like Evernote and Gimmebar but it still doesn't feel right.
Perhaps Mozilla have the answer: https://blog.mozilla.org/ux/2012/10/save-for-later/
I can't be bothered to use bookmarks for these things, having tabs in stacks is much more convenient. If the browser lets me keep a lot of tabs open then I'll abuse this posibility for my personal comfort. If we were to use your philosophy then Chrome should be limited to a certain amount of tabs by design. How about 6, the number of cores in my CPU?
But thank you for the diagnosis dr. Jobs, surely I'm holding the phone the wrong way too. Keep blaming the user.
If I want to ride my bike facing the wrong direction, it's not the fault of the designer that I can no longer steer. I could potentially make it work, but would it ever be reasonable for the manufacturer to add another set of handlebars on the back?
As for your comment about Apple claiming the user was holding their phone incorrectly, they did ultimately provide cases right and therefore admitting that enough users were having trouble to merit a change / fix ?
All said, you are using your browser wrong. Sorry to be the one who has to tell you.
Designers shouldn't be expected to support efficiency on the side they didn't put the bars.
Supporting it would be a waste of developer time. If they run out of ways to make Chrome faster and have nothing better to do then sure, let's deal with this niche problem.
