It's learning a language completely, and being able to communicate in it that makes learning the next easier. People who learn Spanish for a year won't be as fluent in Spanish as they would in Esperanto.
In high school people would take 3 years of Spanish, and be able to communicate somewhat but not fluently. People can communicate fluently in Esperanto in under a year.
You keep ignoring the fact that Esperanto is much quicker to learn. Instead of wasting time learning irregularities, and arbitrary rules you learn to communicate in a new way.
