You trivially and quickly lease them from Hetzner, OVH, or literally any of the other shops that lease out dedicated servers? Or large cloud instances. I don’t understand why you’re artificially constraining this? When we had colo’d servers, we still used cloud services where it made sense (especially S3, scaling storage sucks). I don’t think people are arguing for never using anything but your own equipment.
