>Light is powerhungry and arrogant, but he's also very moralistic. A character that proritizes fear over accuracy would be a different character than Light. He wants to build a better, even perfect, world. And for that, he must have accuracy. Otherwise he's a mere tyrant, something he believes he is not. Somewhat. You're right that Light is extremely ambitious in his goal, but fear is also explicitly his chosen strategy. (Also, Light very clearly leans into being a tyrant. He says that eventually, he wants to start executing useless people as well.) Another thing to consider is that (and I believe this happens in the manga), the news reporting itself responds to the Kira phenomenon, and starts publishing names accordingly. For us, let's think "Top 10 people in the world Kira should kill right now" listicles. The upside is that the information becomes more readily available. The downside is that you (our hypothetical, less-evil Light) may eventually want to exercise some discretion over who's being killed, and that would be where information gets leaked, and that's where I think this strategy might falter.
