Not really; maybe for a particularly motivated individual but not on the large scale. You'll have more succeeds teaching English to large numbers of people because more people will be motivated to learn it, because learning English presently had WAY more immediate short-term utility than learning Esperanto.
Have you tried. I wonder if I'm more qualified to judge or are you.
I know three languages, Finnish is my native and I know both Sweden and English. I'm not good at languages and but Esperanto was incredibly easy to learn. The grammar is so simple and logic.
Words are created from 900 roots by just adding affixes or making compounds. This makes learning the vocabulary incredibly easy.
The number of people who succeed is all that matters because that's all that moves you closer to the finish line of 'universal.' It doesn't matter if Esperanto is the most pleasurable language to learn if approximately nobody bothers to learn it because it has no pragmatic use, because nobody uses it. Network effects work in favor of English and against Esperanto. Esperanto simply doesn't have a snowball's chance in hell.
