Here's a riddle for the Anonymizer:
It's inevitable that an alias system would be developed for any successful cryptocurrency. The alias system would de-anonymize transactions of even the most perfect system because...that's what it's designed to do by voluntary compliance. But, governments would then mandate all transactions be routed through the alias system or you're considered to be a criminal launderer. So it seems no matter what type of cryptocurrency you develop, you will be forced to use the government scaffolding alias system regardless, which transforms the cryptocurrency into an entirely different thing than what it's designed as.
Which is how we arrive at:
https://www.youtube.com/watch?v=9JgvkWRSq7Q&feature=youtu.be&t=47m33sBut with Monero my snoopy neighbors won't be able to see what I'm doing while with Bitcoin they will. What you're describing is at least no worse than the current system. I'd count preserving the status quo as a victory of sorts considering the alternatives.
Unless you give your Neighbors your BTC address or transactions ID, they can't tell what you are doing with BTC either.

Or
If they are really nosy, they will just place a keyboard and screen logger on your PC while you're at work, and then no matter what you use they will know it.

Only real solution is that you have to move away from those neighbors.

FYI:
Are they sleeping with your wife too?
