Many things will end with the destruction of this system. John mentioned the rejoicing of unbelievers, the work of producers of goods, the use of their tools, the light their activities produced (literally and figuratively), and the happiness that resulted. No music, trades, or industry will continue (cf. Jeremiah 25:10). Where there had previously been hustle and bustle, there will then be silence. [source][source][source]
The angel gave three reasons for this devastation, two in Revelation 18:23 and one in Revelation 18:24. The Greek word hoti, "because," appears twice in Revelation 18:23. Each time it introduces a reason. First, men whom the world regards as great have enriched themselves and lifted themselves up in pride because of Babylon"s influence (cf. Isaiah 23:8). Second, as a result of the first reason Babylon has seduced all nations. She deceived all the nations into thinking that joy, security, honor, and meaning in life (i.e, "success") come through the accumulation of material wealth. She used sorcery (cf. Revelation 9:21) to seduce the nations into following her (cf. 2 Kings 9:22; Isaiah 47:9; Isaiah 47:12; Nahum 3:4). [source][source][source]
