I agree with you but it's worth noting that associates are mostly paid to do research. A big component of that is reaching out to startups as "an investor" to learn more about their businesses, even if there is no intention to invest ever in them.
Insofar as identifying great investors that a founder should treat as more than a check in the bank, I've learned through scar tissue that there's a very good qualifying criteria. Every VC talks a lot about being part of the team and how much they'll help you. The great ones don't bother with all the talk. They just start helping.
The Seed-stage ecosystem is also a really weird one. There's a lot of "tech celebrity" investing that distorts the lens of how the machine really works for everyone else, what's misaligned between how Seed is positioned vs. what Seed funds can actually do based on their constraints and incentives. It was quite the learning process for me and my co-founder.
