I wouldn’t mind hving a stargate....
The closest I can come to providing such a wish is in the spherical elevator cars of our Flying Castle. Even the opening is circular.
In the real world, I'd like to have the opportunity to explore a city that has the equivalent, or the equivalent of the turbo-lift.
Imagine being able to be whisked anywhere in your city just as easily as dialing a telephone number.
And don't forget we could do this with available technology.

As for a real stargate ... we might have some trouble with that.
