That doesn't sound logical to me. If Zamenhof didn't intend for it to be a primary language, one you learn from birth, then why couldn't it be used by random people still? There has been trading between countries for much longer than Esperanto exists for, especially in border regions or small countries but also across oceans and continents.
Esperanto is from 1887. I was curious what holidays were like at the time:
> According to Stowe (1994), “many nineteenth-century Americans traveled, and many more participated vicariously in the experience of travel by reading travel letters, sketches, and narratives in newspapers, magazines, and published volumes” (p. 3). Similarly, the appetite for travel in the U.K. was also voracious --https://regrom.com/2020/08/26/regency-travel-traveling-abroa...
So also a goal Zamenhof could intend. I don't know how you get to the conclusion that, because it wasn't intended for my mom to use while I was a baby, it wasn't intended to be used by my mom or me on holiday if we're not "diplomats", unless you call any tourist an international diplomat
