This is what happens when people think too highly of themselves. They come up with their own definitions of well established concepts.
Culture is a thing, and has been extensively studied by people 10x smarter than you.
Winning skills/attributes on the other hand are a figment of your own imagination. While some skills are more important than others and length is important for sure, but champions have been built in various different ways and there is no one formula.
For the last 30 years there is one team that has won the NBA championship without an MVP level talent. ONE!
2023: Denver Nuggets - Jokic
2022: Golden State Warriors - Curry (this is 2 years after they tanked for the no. 2 pick BTW, winning culture and all...)
2021: Milwaukee Bucks- Giannis (after having 1 winning season in the 10 prior to drafting Giannis)
2020: Los Angeles Lakers - Lebron (this is after a decade of constant losing and being a horrible team... all they needed was to get the talent)
2019: Toronto Raptors - Kawhi
2018: Golden State Warriors - Curry, Durant
2017: Golden State Warriors - Curry, Durant
2016: Cleveland Cavaliers - LeBron (yeah... that winning culture of Clevelend)

1980: Los Angeles Lakers - Kareem, Haywood
So Since 1980... The only team that has won an NBA championship without an MVP level talent is Detroit Pistons and they have done it 3 times. 3 out 44 teams. Yes, there are different ways to build a contender, but what is almost universally true is - you need to get a player with the talent, skill and attributes to be the best player in the league. Everything else is pipe dreams and delusions. Unless you are the Detroit Pistons I guess...
If you want to argue that you are better off trying to find that guy by not losing, have at it. We can have that argument too. But lets not lie to ourselves that we are going anywhere without a guy or two(because about a 3d of those teams have had 2 MVP level talents on their roster), who can be THE GUY in any given series...
