That's also a matter of opinion. IMO you falsely equate a fig tree putting out leaves being a sign that summer is near, for a fig tree being cursed for producing no fruit. Jesus comparing our knowing that summer is near when a fig tree puts out leaves with us knowing that "He is near, even at the doors" when we see the signs He gave in the Olivet Discourse,
We already know that Jesus is near and at the doors. He is but the Gospel spoken and believed away from each and every one of us. The signs Christ gives regarding His coming again is not a fig tree showing life, because His coming will be sudden and unexpected for all who are not watching and waiting. His coming again shall be after the tribulation that comes upon the whole earth as the Gospel is proclaimed unto all the nations of the world. Then He tells us when He comes the sun will be darkened, the moon will not shine, the stars shall fall from heaven and the powers of the heavens shall be shaken. Then the sign of the Son of man shall be seen in heaven, and all in unbelief will mourn when they too see the Son of man coming in the clouds with power and great glory. Lastly when He comes again there will be a great trumpet sounding and His angels will gather together His elect from the four winds, from one end of heaven to the other.
Matthew 24:26-27 (KJV) Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be.
Matthew 24:29-31 (KJV) Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
is not the same as cursing a fig tree for bearing no fruit. Leaves appearing on a tree causing us to know that summer is near, and fruit or the lack of fruit are not the same symbol, and Luke's version of the same statement Jesus made in the Olivet Discourse adds, "the fig tree and ALL the trees".
As I've already said, and now for others reading here, I will say again. The purpose for Christ speaking in parables is in every instance that we might know the spiritual Kingdom of God has come. Especially in the beginning days of the Gospel age, many believed and some still believe today that the Kingdom of God will be physically manifested upon this earth. Which is why Christ spoke in parables, to let His disciples know through things that are common that His Kingdom is within you. The parable of the fig tree is no different, the first century Jewish disciples would understand the Kingdom of God is not a physical Kingdom and cannot be seen upon this earth, for His Kingdom is a spiritual Kingdom that is within believers. When these first century disciples see the fig tree that had been cursed showing signs of life, like all trees should, they would know without doubt that the Kingdom of God is near at hand.
Luke 21:29-31 (KJV) And he spake to them a parable; Behold the fig tree, and all the trees; When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand. So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand.
