If it were possible to make a proper tubeless bcycle tire with out goop,

I doubt it. Unlike on most vehicles, you really don't want to carry a
spare wheel/tire.

A proper tubeless tire, able to operate at high pressure, would not be
easy to repair on the road. While sealant will seal small holes, you
need to put in the plugs to seal larger holes, and if you get a sidewall
hole that the sealant can't seal, and that's too big for a plug, you're
really out of luck.

The bottom line is that with tubeless you still need to carry a tube and
pump or CO2.
