Nobody disputes "that a good tool can give you a competitive advantage". What's at dispute is whether other things, such as skill or tacit knowledge in a field, give you greater advantages than this possibly over-optimized tool selection.

Also, why should anyone take your unproven assertion up with Paul Graham? His essays don't support your insistence that the "better" tool wins. On the contrary, I'd argue PG believes a whole host of factors contribute to success before optimizing tool selection down to the last detail.
