From the video it doesn't really seem like tar pit ideas are about technical limitations but more about solving the wrong problem. I don't think the ideas you list are tar pit ideas at all. The value proposition for all of these things is obvious. The technology was hard but once the technology existed it was pretty clear that people would want these things.

At least from my read of the definition tar pit ideas are not just ideas that have been tried and failed but they are supposed to seem easy. Things like the restaurant discovery example are technically very easy to build but the limiting factor to people enjoying buying from restaurants is not a tech platform.
