Web$\begingroup$ (Regular) induction can only tell you that something is true for each natural number. It is unable to pass into the infinite limit. To see this explicitly, try swapping "countable" with "finite", and see that the induction proof works, but the conclusion that $\bigcup_{n=1}^\infty A_n$ is finite clearly cannot be true. $\endgroup$
