I don't see any overt flaw with the fundamentals apart from the bloat. I'm even open to investing in Monero, if the bloat can be fixed. Anonymint has stated that it cannot, but perhaps he can be proven wrong, who knows?
My main issue is with the Monero shills who try to misrepresent where Monero is in terms of completion. Just read your own thread to see the crippling issues that people deal with on a daily basis.
You're conflating - the conversation you were involved in was about the "best" anonymous coin, not the most usable or the most feature-complete. The person referred to ZeroCoin, so clearly they're talking about the "best" with regards to the degree of anonymity provided.
Bloat is something we know about, but not something we're concerned with solving right now, so stop bringing it up. Rehashing it is a strawman argument.
Nothing will be truly anonymous until there is an IP solution (not I2P, which is offers only illusory protection) and open source hardware. Bloat is an issue, no matter how much you try to divert attention away. It exposes your coin to centralization and makes it easier to attack the network.
