Its pretty simple.
Most people on trading forums are quite clueless, and subsequently they’ll lose money playing a negative sum game. There will be a distribution amongst that group, one or two may be lucky, and they may be profitable, one or two may be very unlucky and suffer very heavy losses but as a group, they’ll lose, and the longer they play, the more they will lose.
Money management is the only thing that allows the group to continue playing, until they either run out of money, or they learn what they need to learn. If these people are dumb enough to take a risk in an environment that they dont understand then money management is a very sensible option, its the only thing that gives them the breathing space to learn. Failure to apply sensible position sizing means they’re out of the game before they even begin.
For those with an edge, money management allows them to optimise their returns, so again, money management makes perfect sense.
In conclusion, if your a clueless half wit, then you should pay very close attention to money management, and if your consistently profitable, you should pay very close attention to money management.
The thing is, even if you dont understand money management, or actively apply money management techniques, you are still using a form of money management, even if you only select the default lot size on your trading platform !
The only way to avoid it, is not to trade at all, and you could argue that even that is a form of money management, 0 risk for 0 reward, or 0 risk for more free time and less stress
