Think he said that loans under are useless because any normal people can get it without loans, so most of the lending forum is useless.

I disagree because most kids and teenagers have no credit and in some countries they can't even work, and the dollar purchase power in some countries is really high. In Cuba people survive with $10 or $20, and the chinese workers gain some undreads of dollars/month. India also another country with undervalorized currency, with $3000 you can sustain a family for a whole year.

Plus convert fiat to bitcoin may be expensive, or hard, so might be cheaper take a loan in BTC, then convert later a bigger ammount of cash and repay the bitcoin loand,  than make a small conversion to fiat, then a bigger one later.
