Having some level of transaction fees could be important for preventing DOS attacks.

I also like the idea of forming a treasury from a cut of the transaction fees to fund proposals for future projects from within the community as Cardano and Polkadot have done.

Agreed. Their mitigation approach is somewhat interesting as well though (dynamic PoW [1]). Thanks to the independent nature of the blocks, signing difficulty of the transactions can be raised and lowered dynamically making spam incrementally more expensive for the spammers.
