Bass is not particularly easier to play than any other instrument. A great deal of the music written for bass is easier than a great deal of the music written for guitar, or piano, or whatever. That is not the same thing. How composers choose to use the instrument does not mean there are limits on the instrument itself.
Imagine a simple, root-note bass line, like U2's "With Or Without You" (which, by the way, can be surprisingly difficult to play steadily, error-free, perfectly in the pocket, for four minutes straight). Proves that "bass is easy," right? OK, now imagine playing that same part on the piano. Did the part suddenly become more challenging? Not at all. If anything, it's easier on the piano.
Ok, now think of a common piece of music, like Amazing Grace. Imagine a pianist playing it solo, with chords and the occasional flourish. Would people think, "How skilled the pianist must be to pull that off?" Probably not. If you've learned piano, it's pretty straightforward, lots of pianists of average accomplishment do it every Sunday. Now imagine a bassist playing it solo, with the same chords and flourishes. People are amazed. Why? Because that piece of music is harder to play on bass. So which is the "easier" instrument?
What's "easy" or "hard" isn't the instrument. It's the music you undertake to play on it.
