If you discourage heroism - worse, if you announce that you discourage heroism, the average employee's motivation is going to fall drastically. Everyone will do the bare minimum. Exotic forms of corruption like thrift may even emerge
This is exactly what happens in the wider economy when you discourage heroism in society
Humans naturally want to see the grass greener. If you know all you'll ever be is just a number - worse, if you know you will actually be disapproved of because you tried harder or can do better than average, then everyone (but especially gifted individuals) will perform worse and worse until the company breaks
What this post synthesizes is the managerial's class desire to become the "heroes" at the expense of lump-sumed menial labor performed by faceless employees. It's a parasitical philosophy on work
Imagine you own a company (usually involves years' worth of sweat and tears to achieve some sort of success/profitability). Imagine you hear a manager say "let it fail". I hope the feeling that follows makes it clear that the manager is a sponger
If I own a company where (unbeknownst to me) some function has been hopelessly understaffed to the point they can no longer successfully complete all their tasks, a good thing that could happen is that eventually they do fail at their task and the subsequent investigation into why that happened reveals that they are understaffed and overworked. We can then either allocate more resources or reduce their workload so their tasks become more sustainable. The best way to fix it would be to have good enough communication at all levels that there are no such situations in the first place, but humans are imperfect and mistakes happen.
The last thing I would want is for some "heroic" employee to paper over the gaps until they eventually burn out or leave, after which the company will have a huge problem. All the domain knowledge has been concentrating in that one employee and now that they are gone we have lost that knowledge and will need to rebuild it, probably at great cost if it can be done at all. Like you say, if I built my own company with many years of sweat and tears then I am don't want to let easily preventable issues to have such impact.
As to the first few paragraphs of your post: there are many ways to make employees feel appreciated without also making them into a single point of failure for the entire company.
