Why do not religions remove the wicked man from among the congregation as Paul taught?

(1 Corinthians 5:9-13) In my letter I wrote YOU to quit mixing in company with fornicators, 10 not [meaning] entirely with the fornicators of this world or the greedy persons and extortioners or idolaters. Otherwise, YOU would actually have to get out of the world. 11 But now I am writing YOU to quit mixing in company with anyone called a brother that is a fornicator or a greedy person or an idolater or a reviler or a drunkard or an extortioner, not even eating with such a man. 12 For what do I have to do with judging those outside? Do YOU not judge those inside, 13 while God judges those outside? “Remove the wicked [man] from among yourselves.”
