I think it's ironically telling about your opinion on philosophy that your argument is illogical and boils down to:
1. people who aren't philosophers said some bullshit
2. don't you dare point out people who don't do philosophy shouldn't have their ramblings labeled philosophy
Ayn Rand, a 20th century writer without a university education; Paul Graham, a computer scientist; and the Austrian School, an economics movement, are categorically not entities that have produced or ever will produce philosophy.
That's no a No True Scotsman fallacy. It is a strict application of the definition of philosophy, a deep analysis of certain specific topics. Neither Rand nor Graham is educationally equipped to plumb that depth. And, again, the other name you dropped is not even a philosophical school.
