Some emas you get them via quest (with the exception of the strongest one, the fuji ema. That was only given free for people who pre-registered) so not it's not "obligatory" to buy them.

It's not really permanent, you can still get 3h-3:20 timers (depending on what you're trying to craft) here and there, but it really is just luck.
