Korean could serve as a point of comparison, as modern Korean is written mostly without Chinese characters (you could mix them in if you really want to, but approximately nobody bothers), but it does have spaces between words. And yes, when you have a highly inflecting language, "where do the spaces go" is a very nontrivial problem.
It's a bit easier for Korean as it has far more available syllables (so fewer homonyms), but you could easily imagine these languages making different tradeoffs and ending up in different places.
A lot of material for younger readers uses similar spacing to Korean, like the Pokemon games. It works well enough when you know the vocabulary being used is limited, but even there it gets frustrating.
When you're reading, you're trying to identify a substring and map it back to the unit of meaning, which is effectively the kanji. That works seamlessly with Hangul, because it mostly blocks (as syllables) the same way as kanji, and, as you mentioned, the extra vowels and silent consonants provide more disambiguation. With kana, the length you have to scan to read, and then guess at (using only context to disambiguate), a root word, is a lot more arbitrary.
Mechanically kana is just less compressed, less aligned, and makes it harder to visually identify/scan for units of meaning. Obviously Korean shows that you can make different tradeoffs, but for Japanese losing the kanji would probably necessitate reworking Kana as well - and unless the pronunciation changed, it would probably need to be in a way that represents the pitch accent, which is a modifier on the whole syllable, rather than just a few extra consonants or vowels.
Agreed, I think that's a close analogy and it's wild to me how recently Korean dropped kanji. But I imagine having a lot more vowel sounds made it a lot easier. I've wondered whether the two interacted - e.g. if there were word pairs that had previously used the same vowel sounds, but changed after the switch to Hangul to be distinguishable. Do you know by any chance?
Sino-Korean words are different from Sino-Japanese words in that the sounds are very "rigid": most Chinese characters have one canonical sound, and it is pronounced that way regardless of where it appears (modulo some mostly predictable sound change rules). So, you can't just take a Sino-Korean word and "tweak" its sound to disambiguate - when such a word changes its sound it will no longer be perceived as Sino-Korean at all, which actually happened for some examples such as 산행 (san-haeng, 山行, "mountain + go" = "hike on a mountain") which gave birth to 사냥 (sanyang, "hunting"), a separate word.
What did happen was that we lost obscure words that could only be understood by looking at Chinese characters (because they're used so rarely, or because they sound the same as another more common word) - you could still use them if you wanted to, but unless you also write them in Hanja, it would be confusing, and if you mix gratuitous Hanja into your writing just because you like those words, most young readers will find it pretentious, and I fear, mostly unreadable.
I can't say we lost much by losing these words. Rather, I think it actually forced writers to select less ambiguous words, which is usually a good thing.
(Also, these days most Koreans know much more English than Classical Chinese, so English loanwords can sometimes fill the gap. It helps that most English (or other Western) loanwords sound different from native or Sino-Korean words, so there's less chance of collision.)
