Hard to tell, but with 30 as world class, I think a lot of people are underestimating what they are capable of.
As for what I would focus new points into; I should take the +1dex class someone suggested, stretching and yoga are good for you; Cha boosts would give me an outsized advantage in a lot of situations....so Charisma it is.
It would depend on the tech.
Low tech: e.g. detect and destroy incoming weapons....if a single major power had this, it would bad. They maybe emboldened to use their weapons (both nuke and conventional), as their perfect defense would keep their assets (people, places, weapon systems) safe.
High tech: e.g. directed EMP type weapon that could eliminate any weapon world wide at launch, this would eliminate the MAD doctrine. No-one would be able to launch nukes at anyone. Conventional war would likely have the same driving factors that it does today. But also, it may not get "car bomb" nukes, so nuclear war still possible, just in a very different mode.
Super high tech: e.g. some crazy quantum detection and elimination of weapons that haven't been fired. This would be terrible, basically the group/state that has this power eliminates its rivals ability to retaliate with a proportional response. They instantly become the major threat in the world, this would destabilize any alliances that they have, no one would believe them if they said that they also disabled their own nukes. This would put the world on the edge of WW3 in a heartbeat.
Risk/benefit ratio.
The benefit is X the risk is Y, but the risk increases with excess weight, at some point Y exceeds X. Once the risk exceeds the benefit, it no-longer makes sense to perform the procedure.
From the patient point of view, the likelihood of a bad outcome is above the likelihood of a good outcome. They would be worse off getting the procedure; but likely they are only considering the good outcome and wishing away any bad outcome.
From the doctors point of view, they are considering both outcomes and trying to communicate to the patient that it's not a good option for them. There is also the opportunity cost to consider, they could be helping someone else that is more likely to have a good outcome.
The only really limiting factor is the pressure holding ability of your cylinder wall and the sealing surfaces.
Hey you wanna lift 6000T, hydraulics will do it!
I like to explain it using the word "spend".
Like all levers you spend one quantity to get another. Usually distance/force; you spend distance to get force, or you spend force to get distance.
Hydraulic pressure is pretty crazy, power densities can get insane.

Well at least it is bullet proof....not sure about missile strike proof though.
I looked it up, doesn't seem that bad.
