If the issue of too many DOM elements is memory use, wouldn't it be better to just limit the memory use of a page?

Apologies if this is a really ignorant question as I know very little about browsers/front end development.

It's more than memory use - it causes tree traversals to take longer, which means unbounded style recalculations (common) and side-effecting DOM changes take longer.
