It’s a power thing. In our culture, the power differential between most 16-year-olds and most 30-year-olds is large enough to make the concept of ‘uncoerced consent’ problematic.
In principle, nothing. Positive, worthwhile, sexual relationships can exist between 16-year-olds and 30-year-olds. In practice, there can be a great deal wrong, that cuts against the probability of any given relationship with that age split being a net positive. There are immediately obvious power differentials (several legal and common commercial age lines of increasing responsibility and power are between them[1]), there is a large disparity in history and experience, and probably economic power. These really can lower the downside immensely, while not raising the upside.

I’d put it differently: There’s nothing intrinsically wrong with a 16-year-old and a 30-year-old having sex, any more than there is anything intrinsically wrong with two 30-year-olds having sex. There may be extrinsic factors in either case that make it problematic (somebody’s being coerced or forced, somebody’s elsewhere married, somebody’s intoxicated, somebody’s being manipulative to get the sex). The way our society is set up, the first case is dramatically more likely to feature such extrinsic factors than the second case.
This is one of those “stupid questions” to which the answer seems obvious to everyone but me:
What’s wrong with a 16-year-old and a 30-year-old having sex?
