I think that it should be kept in mind that this was not a ban the Eldar had given to the Númenóreans. It was a ban of the Valar since Manwë Súlimo did not want the Númenóreans to "overpass the limits set to their bliss" [Akallabêth, p. 323] I would say that although they desired an Elvish destiny it was the blessings bestowed upon them that stoked their jealousies as "the desire of everlasting life, to escape from death and the ending of delight, grew strong upon them; and ever as their power and glory grew greater their unquiet increased." [Akallabêth, p. 325] I think their unrest was tied to the gifts they received as High Men and the resulting experiences.
