His/her response is perfectly acceptable and the only reasonable answer. Some of us make significant earning per year on gas (50-60k). To accurately calculate your tax responsibility you would need to calculate the value at time of claiming. If you did this daily it would become tedious at the end of the year.

The only other possible reasons to claim continuously would be to:

1) Claim often in order to sell for other currency or NEO in order to take advantage of compounding interest.

2) Claim often in order to have the GAS available at very short notice in case the gas price spikes and you would like to take advantage of the increased gas:neo ratio for profit.

P.S. - Some if us, especially those that have been around since the Antshare days, have accumulated a large amount of wealth from NEO. Taking taxes into consideration is a prudent and valuable step one can take to avoid potentially losing massive generational wealth due a lack of foresight. I applaud you if your area of residence requires no consideration of a tax burden. However, for those that live in the US and have had very large returns, an audit at cash out time is highly likely and it is significantly easier to be prudent from the get go then when under an audit years later.
