The web in the 90s was an evolving, alive ecosystem. Without the ecosystem, websites that approximate something old-school are standalone entities. Flowers in a vase. They might look the same or even temporarily feel the same, but they are both authored and browsed in an entirely different context.

For example, browsing a website that looks original, but is likely abandoned is a very different experience from browsing it in the 90s or early 00s when it was a part of something big, new and exciting. Even if the content is identical. The same principle applies to authoring.

I have seen countless claims that all the technology that someone could use in the 90s is still available. Regardless of whether it's true or not (mostly not), it misses the point. The social project that was web 1.0 is now defunct.

Paradoxically, the only way to create something equivalent to old-school web now is to invent something entirely new.
