To clarify, yes I own the shares outright.

I believe non-transferability clauses are common these days, ever since some shenanigans with employees selling shares ahead of the AirBnB IPO.

But does it hold up in court? It seems bizarre that I can "own" something and yet have no rights that people typically associate with owning something.

Well, it might seem weird to you, but unfortunately it's not.

Private company shares aren't furniture. They aren't physical property and they don't come with traditional resale rights.

In buying those shares you signed a contract that came with stipulations. One of those stipulations is that you cannot transfer ownership to anyone else. It's perfectly normal and very common.

I just hope you're not realizing this for the first time, now, after you already laid out the capital to exercise those options.

Do you think this is common knowledge though?

I'm pretty sure all YC companies have limited transferability clauses now.

And with the rise of IPO-scale private fundraising, it's possible that a company can remain private literally forever.

This changes the calculus for a young person considering joining early at a startup and I'm not sure that is a good thing for the startup ecosystem.
