Just think about it. The lay man definition of rent seeking is making a profit without putting any effort (i.e. letting someone else carry the burden of earning the profit). Who doesn't want to earn a profit from doing absolutely nothing?

All you need to do is tax the rent seeking and it goes away. The reason why that hasn't been done is that those who would be impacted have good connections with elected politicians. The most humble example is a homeowner who is involved in local politics at the expense of the renter.
