The notion of "Uber for X" was already such a cliche by 2014 that people were joking about it in general-audience publications: https://qz.com/311217/poem-theres-an-uber-for-x/

That poem was published between Coinbase's B and C rounds. By that point Uber had done a series E with a post-money valuation north of $40 billion. If Coinbase wasn't looking at that with envy and trying at points to cast their story in the Uber mold for investors, I'd be amazed, because most other startups of the time were.

That's true, you did say "when Coinbase got started", which I took to mean before the official launch, which must have been sometime before 2012.

But, seems I misunderstood, so my bad.
