Except that's an ideal, not 'compenent'. You don't NEED the 12+ dex, or a con better than 10. Nice? sure, but necessary no. You don't get 4th level spells till much later on. You can happily have a 12 for wis to start with. 10 Int is good, but again, not essential, and the same can be said for the rest of those.
Well, let's see if we can agree on what is necessary versus what is 'nice'...
Strength - NEED 14+ (you're a front-line fighter who is expected to hit on a reasonable basis, deal reasonable damage, and wear heavy armor). NICE is 16+.
Dexterity - NEED 10+ (front-line fighters shouldn't be taking AC penalties). NICE is 12, anything more is unnecessary unless you have mithral armor.
Constitution - NEED 12+ (front-line fighters are expected to be able to take hits). NICE is 14+.
Intelligence - NEED 10+ (especially if you choose something besides human as a race, you don't want skill point penalties). NICE is 12, and anything more means you're a skill junkie or taking Combat Expertise.
Wisdom - NEED 12+ (you only get five stat points over 20 levels, and you will want to raise your Charisma as well). NICE is 14, anything more is gravy.
Charisma - NEED 14+ (anything less doesn't take advantage of your class abilities - which is why you're a paladin to begin with). NICE is 16+.
Totals:
NEED - 24...or your entire stat allotment minus 1 point for standard point buy.
NICE - 40...or more points than any point-buy in the DMG gives.
I think most people like to have a little flexibility in placing stats. The fighter can get their needs met with 8 fewer points than the paladin (14 Str, 12 Dex, 12 Con, 10 Int, 8 Wis, 8 Cha), which leaves a lot more points to flesh out the character. The fighter also has up to three 'dump' stats if they want to maximize fighting capability with the remaining points. The only dump stat for paladins is Intelligence, and you're going to want at least 2 skill points a level, if not more. Just the standard combat functions of a paladin require Ride and Concentration, and a well-rounded paladin has several other skills to add.
Also remember that when the paladin gains levels, 2 extra stat points on Wisdom is 2 less stat points for Charisma or Strength. Since the extra stat points don't worry about the increasing costs you face in point-buy, it's far more effective to dump them all in one stat instead of spreading them about...and to choose a stat that was 14+ to begin with.
