Because God loves the world and desires for the world to believe and be saved.
No one is excluded from the world is excluded.
The Non elect are excluded, for in scripture Gods Love is joined with Election, so whenever speaking of Gods Love, it must involve an Chosen People and in Christ. Deut 7:6-8
6 For thou art an holy people unto the Lord thy God
: the Lord thy God hath chosen thee to be a special people unto himself, above all people that are upon the face of the earth.
7
The Lord did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people:
8 But because the Lord loved you, and because he would keep the oath which he had sworn unto your fathers, hath the Lord brought you out with a mighty hand, and redeemed you out of the
house of bondmen, from the hand of Pharaoh king of Egypt.
NT Rom 9:11-13
11 (For the children being not yet born, neither having done any good or evil,
that the purpose of God according to election might stand, not of works, but of him that calleth)
12 It was said unto her, The elder shall serve the younger.
13
As it is written, Jacob have I loved, but Esau have I hated.
Jacob here, the object of election is Loved,
Eph 1:4
4 According as
he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him
in love:
Jesus is specifically stated to Love His Own in the world Jn 13:1
Now before the feast of the passover, when
Jesus knew that his hour was come that he should depart out of this world unto the Father,
having loved his own which were in the world, he loved them unto the end.
His own equates to His own elect Lk 18:7
And shall not God avenge
his own elect, which cry day and night unto him, though he bear long with them?
And Gods Love is exclusively in Christ Jesus Rom 8:39
39 Nor height, nor depth, nor any other creature, shall be able to separate us from
the love of God, which is in Christ Jesus our Lord.
The Non elect are not in Christ Jesus, never have been, nor will be. They as Esau was are excluded from Gods Love.
Please keep this in mind when you reference Gods Love Jn 3:16
