tkamiya's not a judgmental person, so that's not what he meant at all.
I think he's saying you can get more experience on the same budget using less expensive paper. You can work faster, take more chances and try everything. Then you will make good use of better paper, some point in the future of your journey.
I personally recommend always using the best paper. Once I used expired/old paper and the fog made me think I was terrible. It shattered my confidence. Since then I always print on the best paper and have been very happy about that decision.
I made many prints on a Tetenal RC paper, because it is cheap, and I thought it was a good idea to use cheap paper just for portfolio or as simple, and I wasn't very happy with the result. And I though it was me until I try Ilford Multigrade IV fiber and I realised that the paper make a lot of difference. Cheap paper now only for contact print or to play in the darkroom.
I want try other papers but Ilford Art 300 is what I have on my hands now.
