It takes time (years arguably) to grow somebody from zero experience to being somewhat competent in tech.

Don't get me wrong, it's not easy to go from zero to hero, but I learned a lot through self-teaching and it still paled in comparison to how much I learned in my first few jobs. Modern tech stacks are vast and complicated and have tons of technical debt. Technical fields aren't easy to bootstrap yourself into; eventually people need to be onboarded and get their hands dirty to have meaningful experience. The industry keeps hoping that supply & demand will fix their talent issues but it's hard for that to happen in fields like cybersecurity where doing things in a walled off environment doesn't effectively teach the sorts of on-the-job situations that real experience provides.
