No one cares about abstract let’s make everything equally hard fairness And, as you say, Esperanto is still Indo-European and probably Romance so why not just go back to using Latin or French.
Also the completely irregular spelling. You need to learn every word twice, first how to write, then how to speak. You can't just infer the sounds from the written word. Languages like Esperanto or German are better in this regard, you learn how to write a word and the odds are you'll know how it sounds as well.
