In the VRF case they can't: "This comes with a tradeoff of course and in this case is that you no longer can reach devices on the venue network, which shouldn't be a problem if you're only connected there for internet connectivity."

Ok, but why want you to connect to local networks, when they can't reach each other, wouldn't you just then connect to the upstream router instead?
That's typically all you care about, the upstream router/gateway so you can get to the internet. But it's on the local network, so you need to connect to it.
