"If so, where is the law that established this one religion, and where is the place everyone is required to sign up?"

If you believe this is all the Founders meant by "establishment", you haven't read their words.

They - including Madison on numerous occasions - specifically wrote against the use of tax dollars collected from non-Christians to support the promotion of Christianity. This had nothing to do with the forced practice of Christianity. They also specifically intended that "establishment" would include the use of government office to adopt Christianity as the state-sponsored faith. Reading "establishment" to mean "complusory adherence to one faith" is a far more narrow reading than the one set forth by those who wrote the 1st Amendment.

An establishment of religion is a state church. There isn't one.

Nor is there any compulsory worship of any variety required when one walks past Judge Moore's piece of art.

No more than when you walk past any other piece of art.

Smokescreen! Cite specific references.

All of the founders spoke out strongly against using tax dollars to support anything but the enumerated functions and powers as listed in the constitution.
