The catch is that bare metal is SO cheap and performant that you can buy legions of it and have it lying around. And datacenters, their APIs and whatnot advanced so much that you can even have automations that automatically provision and set up your bare metal servers. With containers, it gets even better.
And, lets face it - arent you already overprovisioning on the cloud because you cant risk your users waiting 1-2 minutes until your new nodes and pods get up? So basically the 'autoscaling' of cloud has always been a myth.
