I can't speak to Helium. I would ask someone else to jump in if they know that system.
Again, if you look at why Ethereum was created to be different from Bitcoin, you see it's trying to build a settlement layer for any asset or any activity. Those assets can be real-world tokenized dollars, real-world tokenized real estate or crypto-native activity like on-chain trading, which are self-referential to their own ecosystem or NFTs in the metaverse. The question is what underpins that system, and there you need a token.
Does someone want to jump in on Helium?
