I'm not sure either of these quite gets it. I believe David has confused the words delectare and deligere. Delectare does not mean 'choose', and the form he supplies is neither subjunctive nor infinitive. My concern with Hunter's answer is that I'm not sure that the noun 'optio' can be used as he uses it.
I suggest the following two ways-
lecti ligantur or delecti deligantur. Both mean 'the chosen are bound', although it seems to me that deligantur usually refers to literal binding; so maybe the first is better. That's how I would maintain the phonetic repetition of 'chosen' and 'choice'.
If you want to be clearer, you need to say something like 'lectis nolle non licet' (It is not permitted to the chosen to be unwilling') or 'lecti coguntur' (The chosen are compelled).
Also, lectos necessitas premit (Necessity presses those chosen) would indicate that nature itself insists on compliance. It depends on the context.
