English as the only official language in the world.

Thank you so much, THElittleRISK, for the fast engagement, I am starting to really like this website!!My next argument will also be in two parts, rebutting Con's two arguments from my own point of view.First, I completely agree that English ranks third in number of native speakers, but what I do find necessary to rebut is Con's argument that English would not be the easiest language to teach to the world. Mandarin Chinese, as number one language by its native speakers, can never be as easy to learn as English, despite the fact that the English language also has a fairly difficult orthography for beginners, but don't forget that English is written with an alphabet and isn't tonal. Also, 98-99% of Mandarin Chinese speakers are found in mainland People's Republic of China (as we all know, Taiwan's and Singapore's population add up to some 30 million people (1), whereas the PRC's population is 1,353,000,000 people (2)), which is a single-party socialist state and overall, people have little interest in learning Mandarin Chinese, because it's the Chinese who have interest in exporting to overseas (Made in China stuff), it's not the other way around. As for the Spanish language, it's practically the same. Spanish is indeed spoken by more than 500 million people as a native language, but the countries that speak it are not so developed as those, who speak English as a mother tongue (USA, Canada, Australia, the UK). And you have probably misunderstood my first argument, I didn't say the English language should replace the mother tongues of the different countries, but instead, to become an official "world language", i.e. a status never given to a language before. That means that it would be mandatory for all citizens of the world to learn it as it's mandatory to learn their own languages. Following that statement, the world will not become a more monotonous place, but instead, a more interesting one, and a more easier one to live in, because everybody knowing English will be ten times more at ease to communicate with his fellow human beings all over the Earth.Why, in my opinion, should it not be Esperanto:English currently acts as a "lingua franca" between peoples since the rise of English diplomacy in 1919 (3) and why is that? Because, like I said, currently one of the most powerful countries are all speaking English as a first language. There are thousands of intercontinental enterprises whose CEOs are English-speaking, English still is the language of diplomacy, the language of almost all unions and organisations and it has been their official language for a long time, that means the people working there whose first language isn't English are now used to it, it has become their second language, because they are obliged to speak it fluently.Now if Esperanto actually was based on some West Germanic language (something like modern Scots or Dutch, which is a little less close to English), I would agree that it could be made the 'official language' of the world, and not English, because some of the people might consider that a bit chauvinistic and anglophile from the part of the English speakers, and it would be a thousand times easier to learn for the masses, because up to 750 million people speak FLUENT English as a second language (4), and Esperanto is based on Latin language stems, and there are A LOT that are different of those in English (of course, if you speak a Romance language, i.e. French, Spanish, Italian or Portuguese, it will certainly be easy, but people who speak a Romance language actually use it to speak in the country that uses that language, as you can never be sure if the interlocutor speaks French, Spanish, Italian or Portuguese, whereas one can be sure that at least a quarter of the human population can at least hold a basic-to-intermediate conversation with English, those people are not officially counted). This is why if people decide that English should NOT be announced as the official language of the world, the conlang that should take that place has to be based off English or off a close relative of it.Sources:(1) https://en.wikipedia.org...(2) https://en.wikipedia.org...(3) https://en.wikipedia.org...(4) https://en.wikipedia.org...
