I thought you were a bit harsh by calling it entitled, but then I saw “Then rent an office or subscribe to a co-working space? What? I get paid to work, not to pay for it.” Right afterwards, so I’m included to agree that there is definitely some kind of entitlement going on.
The irony is that even as this person complains about “paying to work”, libraries are often immensely expensive and he pays for that library with every paycheck and tax bill.
