Actually the issue of pressure is much more complicated
Yes, you can increase the pressure. But then your flying tube in a low pressure environment may explode
Or it'll suffer a bigger expansion/contraction with every cycle and hence less cycles or metal fatigue and failure at 37000feet (passenger won't ask for a refund as they will be unable to do)
So the "cabin altitude" is really a balance between mechanical resistance and people not passing out (though this may be a good idea with some passengers)
