The problem I have is however that anyone with any name can make use of that point

What do you mean by the part in bold. Give a code example of where a player can currently use the point of another player.
Because now, the only thing you have in the given code, is the creation of the file and the accessing of the personal point.

EDIT:
You don't need this when creating the point.

Code:

HousePoint[playerid][PosX] = dini_Float(file, "X");
HousePoint[playerid][PosY] = dini_Float(file, "Y");
HousePoint[playerid][PosZ] = dini_Float(file, "Z");
