Its basically for their own colleagues and ilk, and the discussions and arguments they have are so frivolous its unimaginable and cannot help any ordinary average joe muslim in any way shape or form.
That's the point. It's not supposed to be for the average joe. If you go sit with accountants, lawyers, biologists, neurologists, etc you won't get what they are talking about either.
Unfortunately this is the same position our firqabaaz and maslak parasts moulvis also hold. Quran khud mut pardna verna gumrah ho jao gay!
Nowhere he says you can't read the Quran on your own. He's clearly referring to books written by Scholars for Scholars being read by the common folk. That's where most go astray.
That's like saying who needs a doctor you should read a few medical books and treat yourself. These professional doctors don't know anything. Exceptions are always there but exceptions never become the rule.
The problem these days is that everyone who reads a few books thinks he's a scholar and knows better than those who have spent their entire life in pursuit of knowledge and sharpening their skills. This is arrogance and nothing more.
Personally, with each passing day the more I learn. The less I know.
We are in the information age. Access to widespread information has made the masses dumber and not smarter.
Where did Pakistan fail? The local mosque clergies are where we fail. 99.9% of Pakistani's have never availed them to the company of true scholars. Then it is again one of the signs of ends of times that we'll have lots of people who recite/read the Quran yet very few who will understand and implement.
Hamza Yusuf is in a league of his own and a true scholar who always keeps his knowledge updated and relevant to current times.
As for your friend you should recommend him to learn some sales and marketing if he wants to make money. Friends are supposed to build each other up and not tear one another down. No wonder he's upset with what you said.
