Thoughts are things.
If we share thoughts we share things.
Things can be capital.
We increase our capital by sharing and maintaining certain thoughts that are accepted as truth by others
Like Bitcoin being sound money.
Knowledge is not capital.
If I share knowledge with you, we both have it. Neither of us is deprived its use.
We cannot share capital in the same way.
The Use of Knowledge in Society by Hayek will set you straight.
