They lived in a different culture and time. It is wrong to think of them (as some do) simply as foretellers of the future or even as men in a purely religious profession. These guys were political activists. If the regime in power found them credible, then they were appointed as political advisors. Otherwise they were anti-government activists. The attention-grabbing stuff that Ezekiel and Jeremiah did reminds me of some of the antics sixties' anti-war protestors did in demonstrations against the Vietnam War.
In October 1967, David Dellinger of the National Mobilization Committee to End the War in Vietnam asked Jerry Rubin to help mobilize and direct a March on the Pentagon. [ 4 ] The protesters gathered at the Lincoln Memorial as Dellinger and Dr. Benjamin Spock gave speeches to the mass of people. [ 5 ] From there, the group marched towards the Pentagon. As the protesters neared the Pentagon, they were met by soldiers of the 82nd Airborne Division [ 5 ] who formed a human barricade blocking the Pentagon steps. [ 4 ] Not to be dissuaded, Hoffman vowed to levitate the Pentagon [ 5 ] claiming he would attempt to use psychic energy to levitate the Pentagon until it would turn orange and begin to vibrate, at which time the war in Vietnam would end.

He was on the right side of history, even if he really didn't have divine foresight of the future, he correctly understood the ramifications of a rebellious course against Babylon.
