I understand where you're coming from (in your frustration at least), but where most academic papers are concerned this isn't an issue of attempting to sound "smart", it's an issue of audience.
The audience of most academic writing is other experts in the same field, and the goal is to convey the contribution. Without the necessary abstractions, and therefore the requirement of understanding them, the task of composing works on meaningful contributions would be absurdly difficult.
