I always understood it to be that things exist to be fruitful and multiply. In a sense, a person who does not love, who doesn’t multiply goodness in the world as Jesus modeled, was like the fig tree. Such things could be thought of as cursed, withered and twisted versions of what they could and should be.

I am not a Bible scholar though lol.

I saw a guy waving a sign to spread awareness, "God Hates Figs"

Or something like that

The understanding I've generally heard, and which seems supported by the context, is that the fig tree symbolises the unfruitfulness of God's people. This is particularly apparent in that both Matthew and Mark record it as happening alongside Jesus casting out people trading in the temple (Luke records the cleansing of the temple but not the fig tree thing). It is then followed by Jesus telling a series of parables against the religious leaders. There may also be a relation to the parable of the barren fig tree earlier on in Luke 13.

Possibly an extremely contemporary metaphor, where the first-century audience was expected to recognize it as reference to a specific authority figure.

Makes him more relatable.

I too think this story is very confusing. I think it's a metaphor saying something like the time / the people aren't ready for him yet or something
