Encoding English into text is simple, and has always been simple. Correct spelling is a difficult, but even with that in mind, if you can speak English, you can pick up reading English fairly easily.
Ideographic text, while really neat and fun to learn, does take a long time and a lot of effort to learn. The barrier to entry is much higher. And you may wonder, maybe it would be better to use that precious early classroom time learning something else, and have a simpler writing system.
But who can read, who can write, to what level they can do so, and what other learning has necessarily accompanied that process, is central to how a civilization progresses over time.
With many factors in mind… yes, ideographic writing systems are just fine. In fact, they might just be essential for a long lasting civilization.
