Are Holodecks Possible in the Future of Star Trek?

[EnumaElish]

When I watched Star Treks decades ago. I thought the Holodeck was actual matter. But then the concept is not so hard to understand. They can explain the gravity and matter are simply information.. so what the holodeck does is simply precipitate form and geometry (matter and gravity) from the informational domain (sub quantum vacuum). This would make a more imaginative Star Trek .So why didn't they propose it?

They proposed it but the joint congressional subcommittee demanded a cheaper alternative at the expense of quality. As a result of lower quality they got extra bright colors, the occasional flicker, and possible "field memory" (the spacetime equivalent of screen memory).
