Because it lacks specific criticism, your comment feels a lot like shallow dismissal template that can be deployed against any position one disagrees with, e.g. "This is what $(non-DIYers) tell themselves to feel better about letting $(electricians) have free reign with their money". Substitute with PaaS, banks, healthcare providers as needed.

My comment is shallow because it is not attempting to prove that active investing is better. It's saying, "I've heard people blurt out a list of reasons not to actively manage their portfolio and it's always been from a position of laziness or fear". There is a way to advocate for SPX or VOO or Fidelity 2045 and it's not by saying that these are the optimal strategies.
