I work in HFT. He is completely correct

I always laugh when people say Robinhood is a good thing for society. Their zero fees, cool app, and gamification of trading is simply ushering fools into a casino

Cool. What's the best way to minimize transactional costs when buying ETFs (as a buy-and-hold strategy)? E.g. Should I only purchase marketable round lots? Can I do any better than Fidelity/Interactive Brokers for price improvement? Any tips to make my trades as efficient as possible? Or would you avoid ETFs altogether and just purchase mutual funds directly from Vanguard, without any transactional costs? Thanks!

You are pretty much already there

For the majority of people, I would recommend just buying Vanguard funds

If you really want to trade anything else, IB is the way to go

Gotcha, thanks! As for lot size, I know I mentioned round lots, but I typically trade odd lots out of convenience. What does this cost me in practice? Am I missing out on any investor protections that only apply to round lots?
