The post was written for people who are interested in starting a company. If you're not in the financial state to be able to do so, then blogs about starting companies are probably not for you.

"Reach out to all of your rich friends and family" is privilege, which I think is also fine to call out but shouldn't completely be ignored. Your individual "privilege" might be from participating in a veteran's group or knowing someone with special needs. Something that puts you in a unique position to address a problem better than others have. Having money is one of the most generic forms of privilege, so offering insight to when and how to best use it is useful.
