[MCU] How does the Hand get around the Law of Conservation of Ninjutsu?

With the exception of Earth-1218, the Law of Conservation of Ninjutsu is a universal constant. However, in their fight against Daredevil, Elektra and Stick, the ninjas of the Hand seem to do pretty well despite being masked and having overwhelmingly superior numbers. How is this possible?

It absolutely applies to this universe. 

Just think of Matt's first encounter with a Hand ninja, the one where a single ninja has him outclassed and wrecks his shit (before he gets a lucky break and sets the ninja aflame).

You're simply misinterpreting how conservation of ninjutsu works.

One ninja is very dangerous for Matt, but he can hold his own and get lucky. When there are dozens of ninjas he can hold his own, even if it's a difficult fight, as long as the numbers don't completely overwhelm him. Same difficulty, with more ninjas, textbook conservation of ninjutsu.
