What’s the point of clipping stuff? I keep only personal stuff in my vault (for example, things that happened to me, whatever I know about people that are close to me, places I like, events I want to remember). Because if it’s something you found on the internet… it means when you need it again, you can go and find it on the internet again?

Unless you have a constant paranoia that things you liked will disappear from the internet one day, in this case I would download and archive stuff, which I don’t consider “clipping” anyway and don’t store in my vault. I treat Obsidian vault as my diary, it’s for personal things, not to shove thousands of publicly available things into it.

Sorry I don’t mean to be rude, I’m genuinely curious about what are you trying to achieve and what problems you are trying to solve and why does it need to involve obsidian?
