Imagine you are on a terrace, with the heat sticking to your skin, a glass with ice in front of you, and you ask your companions if they want to go for a swim. One of them replies: “No, thank you. Consequently, I will proceed to leave the establishment.” You will probably look at them strangely, not because you haven't understood the sentence or because there's any problem with the syntax, but because it's hard to imagine someone speaking like that in that situation. The most probable thing would have been for them to say “No, I’m going home” or simply “I’m leaving”.
