I'm finding 4" displays for $36 and 7" for under $70.

For a 4x16 LCD, the 2" displays are probably most comparable, and are in the same price-range as the equivalent LCD (about $8--$12).

2" e-ink multi-colour displays with far higher resolution ... are about $20.

I'm no fan of E-ink's patent monopoly, but you're being ever so slightly disingenous / unreasonable here.
