>> What's supposed to be wrong with this?
It is over-reach.
What if the policy stated that all conference participants could only eat vegan foods?
Or that the conference had to have all energy use with 100% green energy sources?
Or that all conference materials had to use the English language?
Or that the conference proceedings must pause for the call to prayer?

Good luck getting everyone around the world to agree what the 'basic requirements' should be.
Why not leave those details to the conference organizers?
By the way, in some states, it's legal to carry even where private actors forbid it, so you could attend a conference where they are "forbidden", and there could be people legally carrying anyway. People will never know.
in most states, the decision to permit firearms on-site is made by the facility owner and must have legal posted signs
so if a hotel in Texas doesn't have legal signage disallowing carrying on-site (no signs means you can carry), you can't just impose those rules for your own function (the correct course of action would be to hold your conference at a facility that operates policies you agree with)
I sure as hell wouldn't want to attend conferences where firearms are forbidden. I don't want to be an easy target.
The idea that carrying a firearm is inherently dangerous is absurd.
Banning all weapons from conferences? No need for that. Having an evacuation plan? Only if required by local health regulations. Ensuring the physical safety of participants? If you feel like it. Allowing firearms? ABSOLUTELY NOT!
Carrying firearms around is already a non-issue in most of the world, so it's pretty weird to focus so much on it.
Not sure which places in the world you are referring to, but it's illegal in most places, and where it's not illegal, it's generally frowned upon to be carrying guns, unless you're actively visiting areas where it's advisable to carry a gun, but those are not places you stay for long in, certainly not to live there long-term, more like areas you have to pass through.

I sure as hell wouldn't attend a conference where firearms were permitted, and I'm fairly sure even the NRA have organised events where carrying firearms or other weapons is prohibited.
I don't think it's unreasonable to try and ensure events marketing themselves using a Rust trademark are organised according to some basic requirements.
