Super guns have been attempted. Space guns comes up fine on google.
What you are missing is the shock of initial launch. In a gun the projectile goes from 0 to its orbital speed virtually instantaneously. Very little other than solid objects survive the massive g forces involved. Certainly not people.
Project Orion lifted of slowly, each bomb pushing the craft (with a massive pusher plate to absorb shock for the payload) just a little higher and faster. That why it took many bombs not just one. A single bomb can launch something pretty high but that wasn't the Orion design because they wanted the payload to be less robust than a solid object.

And this part too. Thank you, kind poster.

No the g-forces wont exclude humans. A proper Orion craft has a payload section and a pusher plate. The pusher plate and the payload are separated by massive shock absorbers to minimize the forces exerted on the payload.
>Two shock absorber designs were explored. The first consisted of three donut-shaped gas-filled cushions, each one meter high, looking like a stack of tires. Six-meter high aluminum pistons rose from these absorbers. This system would limit peak G forces to 3 to 4 G's. But it would be a bumpy ride for the passengers. Therefore the second design was more complex but allowed the shock absorbers to operate in synchronization in order to further even out the G-forces. This would limit peak forces to 1.5 to 2.0 G's.
1.5 -2.0 Gs is less than the 6Gs of early rockets and the 3 of the shuttle.
$200k and radiation over an area, downwind from the fallout and environmental damage noticeable across the world. We didnt stop Orion strictly because of the treaty. If it had been viable (ie worth the environmental damage) we would have negotiated it into the treaty.

What you are looking for is explicitly spelled out in the Space gun article that I already linked and you couldn't find in the section Technical Issues.
>the acceleration would theoretically be more than 1,000 m/s2 (3,300 ft/s2), which is more than 100 g-forces, which is about 3 times the human tolerance to g-forces of maximum 20 to 35 g[5]

You are the one looking for help. Read the footnotes. Do the math. Stop telling people they are dumb because of your own laziness and ignorance. The information is right in front of you. Not our problem that you dont want to believe it.

Orion’s $100k bombs never existed, it was a design objective that they’d have to achieve (and a very hard one) if they wanted it to be economically viable
