Right - the words themselves aren't as important as the concept. Any replacement word will suffer the same confusion. There's a reason that the language of debits and credits has largely remained the same for the past thousand years, and the language describing accounting is unlikely to be 'optimized' by first-principles CS concepts from people only loosely familiar with the field.

Well said. It's actually not complicated or arbitrary. It also works effectively in practice over the gdp of the known universe. If you are savvy enough to be interested in and understand the different computing approaches to double-entry bookkeeping, one can assume the whole DR/CR concept isn't beyond you.

There's a reason, but it's definitely not that any replacement is just as bad since that's close to an impossibly strong statement
