The constructed language thing is wrong. The most spoken constructed language is Bahasa Indonesia (Indonesian), which has 270 Million speakers and was in fact constructed to standardize all the different languages and Malay dialects across Indonesia.
The second most spoken language is Modern Hebrew. Modern Hebrew was an attempt to resurrect ancient hebrew by early Zionists in the late 19th century, but due to a lack of information it largely ended up becoming a constructed language. It has roughly 10 Million speakers.
Esperanto only comes at place 3 with roughly 2 Million speakers.
Bahasa Indonesia and Modern Hebrew are often not recognized as constructed languages, because they were built based largely of a single other language (Malay, Ancient Hebrew), they are still constructed though.
If you go by your logic of Indonesian being constructed, any language that has a highly standardised form is "constructed". English went through a similar process during the popularisation of printing.
