I agree that if you "burn your ships", language learning can be surprisingly easy and natural. This is one reason I think there's a relatively low level of Danish proficiency in adult immigrants: it is virtually impossible to burn your ships in that manner, because ~all Danes speak fluent English, and generally prefer to speak English to foreigners vs. attempt to understand poor Danish. If someone explicitly asks to keep the conversation in Danish, then people will typically oblige and attempt to understand the learner's Danish, but as soon as the person goes to a restaurant or even a government office, it'll be immediately English again unless they ask each time this happens (and even then the person may just honestly not understand them, because Danes are not good at understanding mispronounced Danish).
