But then there's the guy who added all the mass and energy of the observable universe, calculated its' Schwarzschild Radius, and came up with 13.8 billion light years.

There's also how our observable universe's Hubble Horizon acts like a black hole event horizon, the way in which even the speed of light is insufficient to escape beyond.

A lot of the math inside a black hole is eerily similar to the math of our own horizon, as traced by the age of the universe plus the speed of light.

That is simply how horizons work. It's nothing magical about our universe. It's discussed in every astrophysics course worth its salt year one...

PBS Spacetime has many episodes on horizons and this very concept comes up a lot. It's also equally probable using such simple logic that we are in a white hole given the effects of dark energy, but the truth is they are very different sorts of horizons.
