If there’s so many people ascending the mountains, why not install some real infrastructure? Anchor a cable line so that at a minimum, cars full of supplies can be winched up and down. Install some shelters along that route where there would be staff, small heated and pressurized areas, etc.
And, most importantly, since the cable hoist system would be able to move up supplies, every climber would be required to check in at each waystation, have their pulse ox and core temperature checked, and get oxygen refills as necessary.
This would make it much safer - as I understand it, the primary problem killing climbers is just running out of oxygen tanks because they are forced to carry them themselves and can only carry a limited quantity.
