Is it? Would it be more fulfilling for me to try to understand the proof by Wiles? I realise this would take a lot of study.

"Is trying to prove Fermat's last theorem by an elementary technique pointless? Is it?" Only if one fails to make a point.

But it does appear that he published proofs of the theorem for n= 3 and n= 4 after he wrote that reference. If he had a proof for all n, he would not have done that.
