How does an enacted parable not make any sense? That's what it is - Mark doesn't create his sandwich stories for nothing.
Mark 11 with several verses before and after the fig massacre:
11And Jesus went into Jerusalem and entered the temple [[
b]enclosure]; and when He had looked around, surveying and observing everything, as it was already late, He went out to Bethany together with the Twelve [apostles].
12On the day following, when they had come away from Bethany, He was hungry.
13And seeing in the distance a fig tree [covered] with leaves, He went to see if He could find any [fruit] on it [[
c]for in the fig tree the fruit appears at the same time as the leaves]. But when He came up to it, He found nothing but leaves, for the fig season had not yet come.
14And He said to it, No one ever again shall eat fruit from you. And His disciples were listening [to what He said].
15And they came to Jerusalem. And He went into the temple [area, the [
d]porches and courts] and began to drive out those who sold and bought in the temple area, and He overturned the [[
e]four-footed] tables of the money changers and the seats of those who dealt in doves;
16And He would not permit anyone to carry any household equipment through the temple enclosure [thus making the temple area a short-cut traffic lane].
17And He taught and said to them, Is it not written, My house shall be called a house of prayer for all the nations? But you have turned it into a den of robbers.(
B)
18And the chief priests and the scribes heard [of this] and kept seeking some way to destroy Him, for they feared Him, because the entire multitude was struck with astonishment at His teaching.
19And when evening came on, He and [
f]His disciples, as accustomed, went out of the city.
20In the morning, when they were passing along, they noticed that the fig tree was withered [completely] away to its roots.
21And Peter remembered and said to Him, Master, look! The fig tree which You doomed has withered away!
22And Jesus, replying, said to them, Have faith in God [constantly].
23Truly I tell you, whoever says to this mountain, Be lifted up and thrown into the sea! and does not doubt at all in his heart but believes that what he says will take place, it will be done for him.
24For this reason I am telling you, whatever you ask for in prayer, believe (trust and be confident) that it is granted to you, and you will [get it].
25And whenever you stand praying, if you have anything against anyone, forgive him and [
g]let it drop (leave it, let it go), in order that your Father Who is in heaven may also forgive you your [own] failings and shortcomings and let them drop.
26[
h]But if you do not forgive, neither will your Father in heaven forgive your failings and shortcomings.
I missed it apparently. The fig tree seems unrelated to the temple. Please show me what you mean.
