In finite sets or potentially infinite sets this is true, of course.
Reason: Every line n can be checked since we can go to line n+1.

In actually infinite sets it is not true, since there must be more
lines than every number n can reach. Remember: Beyond every n there
follow more loines than can be reached by a natural number or can be
measured by a natural number or can be enumerated by natural numbers.
