Yeah without interest people won’t lend.
Angle 1: Of course we aren’t really going to forbid people from offering loans with interest to people they would never otherwise lend to? Is that feasible? Is it good? I think no and no.

Angle 2: I think there is nothing wrong with an individual aesthetic of not lending with interest. Living in accordance with this aesthetic may even be a good thing. I wouldn’t lend to family with interest for example. I also like the idea of only giving to family, not lending.
