If you read what I wrote first I said that wind can increase ground effect which lowers the speed to land, BUT if you come in at the normal speed for landing not indicated you would be to fast and take longer to stop and even get the plane on the ground.

This is just getting silly. Increasing ground effect does not cause a plane to land shorter. That is just a contradiction and misuse of standard terminology.
An airplane only knows how fast it is flying through the air. It has an AIRSPEED indicator. (With GPS you also know actual ground speed but for this discussion that doesn't matter.)
Wind does not increase ground effect. What you seem to be talking about is the normal precaution of landing at slightly higher speed when you have a strong headwind. Actually what you are doing is giving yourself a buffer against gusts and the wind temporarily dying leaving the plane with less than enough airspeed, possibly producing a stall low to ground, etc.
You also seem confused when you say
"BUT if you come in at the normal speed for landing not indicated you would be to fast and take longer to stop and even get the plane on the ground".
Even if you were to decide to always land at the same groundspeed (foolish), you will still stop shorter due to the headwind. It doesn't make sense to always land at the same ground speed - air speed is what matters.
No matter how you slice it, a headwind will *decrease* the distance required to land and this is not ground effect.
