Small farm using Booker T. Whatley's 10 Commandments--valid?

Need some guidance: Booker T. Whatley's 10 Commandments: are they still pertinent to a permaculture, making-a-living SMALL FARM? Anyone still applying them?
I'm a newbie but seek to purchase land (small scale) to support myself and family plus generate an income. Whatley seems to have it all wrapped up--but his book is 30 years old! Looking for an update.
Thanks.

I had to look up the commandments Greg, Here they are from wikipedia.

Booker T. Whatley

Thy small farm shalt:
I.Provide year-round, daily cash flow.
II.Be a pick-your-own operation.
III.Have a guaranteed market with a Clientele Membership Club.
IV.Provide year-round, full-time employment.
V.Be located on a hard-surfaced road within a radius of 40 miles of a population center of at least 50,000, with well-drained soil and an excellent source of water.
VI.Produce only what they clients demand—and nothing else!
VII.Shun middlemen and middlewomen like the plague, for they are a curse upon thee.
VIII.Consist of compatible, complementary crop components that earn a minimum of $3,000 per acre annually.
IX.Be 'weatherproof', at least as far as possible with both drip and sprinkler irrigation.
X.Be covered by a minimum of $250,000 worth ($1 million is better) of liability insurance.

Thanks Miles--yes, these are the 10 Commandments from Whatley. Is anyone still using them? They seem very sensible to me.
For example: no middle men or women; only sell directly to the client.
For example: create a client purchase club wherein the clients pick their own produce on one's farm; this privilege is secured through a subscription; and, the produce picked is payed for when it is harvested by the client.
Apparent benefits of these two points: no (or minimal) investment in harvesting machinery or staff.

Obviously there is more. Are these things still valid?

Thanks.

PS -- yes, some of the points are a bit aged, i.e. the insurance and perhaps the distance to a population center. These can be addressed.
