You absolutely should use proper erasure in all situations! It's the opposite of confusing. :) (lojban for the opposite of confusing, btw: "to'e cfipu")
In English we'll say various things to indicate erasure, such as hesitation words like "uh" or "um", and negation words like "no". For instance you might say: "I went to the bank.. uh, wait, no.. the park." A combination of tone, uncertain words, and often a bit of backtracking shows that you're making a correction.
The equivalent erasure word in Lojban is "sa", and after practice it's just as natural to use in speech (though it is not in fact easily machine parseable). "sa" simply means "erase backwards far enough so that the next thing I say fits and makes sense."
The example above in Lojban would be: "mi klama lo banxa sa lo panka". Since the correction starts with "lo", you know that it only goes back as far as replacing "lo banxa". If you said "mi klama lo banxa sa citka lo plise" (I went to the bank, uh, I mean, ate an apple), since after the "sa" is a selbri, the selbri "klama" is erased as well. If you say ".i" after "sa" it erases the whole sentence you started to say.
Proper erasure is indeed used in all kinds of Lojban conversation, and turns out to be very clear and useful. :)
