Cybersecurity is (seemingly) pointless (Devils Advocate rant)

This title is bombastic - I know. I don't believe it 100% - but there is a little sentiment that is true. I am open to criticism, so please criticize me. Hear me out. I am a Cybersecurity "Professional" as one might say, so I am not just a random person ranting... I love my industry and have a passion for protecting the cyberspace. However, when I gauge the ability of persistent threats and the resources us "good guys" have to protect against them, on a large scale it is seemingly pointless. Side note: It's not even about a lack of resources. I think even if we had enough seats in chairs and money to go around, it still wouldn't be enough. 5 creative malicious actors can out perform 5,000 Cyber analysts + Security orchestration, automation, and response (SOAR) programs - it's not even a comparison. We can protect a network from very specific threat vectors, like phishing e-mails or malicious downloads, which low level attackers may employ against
