Because most people don't know what they're talking about.
Being complete - Offense / Defense / (Points, Rebounds, Assists, Steals , Blocks)
Offense - Jordan holds the records for post ppg in both the REGULAR season and PLAYOFFS, the latter by an absolute mile.
He has 10 scoring titles. Lebron has 1. Nuff said.
Defense - This one is not even debatable. 9 time all first team NBA defense , tied for most in NBA history. multiple seasons of 200+ steals and 100+ blocks. First player and one of only 3 players to do that. Jordan did it in back to back seasons. 3 steals titles. NBA Defensive player of the year.
Lebron only had a relatively short peak as a very good defensive player and even in that peak , he was nowhere near the defensive player Jordan was who was a monster on defense for almost his entire career.
Offense + Defense - The fact that Jordan won the Defensive player of the year and Scoring title in the same year tells you everything you need to know. Of course no one else in NBA history has done that.
(Points, Rebounds, Assists, Steals, Blocks) - So Lebron has this reputation as a stat stuffer but some don't seem to know that Jordan is easily the greatest stat stuffer in modern NBA history.
Basketball Statistics and History | Basketball-Reference.com has a stat called "GameScore" - which analyzes every statistical component of individual games, from points, rebounds, assists, steals, blocks , FG%, efficiency and FT%. all combined into a number. This link does a good job explaining it:
Game Score | NBAstuffer
40 or more Gamescore for an individual game represents and all time great game. Guess who has by far the most in Modern NBA history ?

(
Jordan has 56 total such games , Lebron has 26)
What that means is Jordan is the greatest stat stuffer and has the most impressive game stats of any player in the modern era (since steals and blocks were not accounted for going back to Wilt and Russell's era in the 60's)
Basketball is not just about Points, Rebounds and Assists in judging how "complete" or "all round" a player is. If that's the case, Larry Bird was a more all round player than Jordan.
Never mind, there are also positional differences between small forwards and shooting guards and what they contribute to the team.
Looking at the total package I presented above, Jordan wins in all of them over Lebron.
- Offense - Jordan
- Defense - Jordan
- (Points, Rebonds, Assists, Steals, Blocks, FG%, FT%) - Jordan
Jordan is the most complete player of all time, clearly a better all round player than Lebron and its pretty clear if you actually know basketball and you've done some research.
