It appears to be a simple thing. Proposing a tax to benefit the blockchain as a whole is sound. Some taxes are not warranted. Taxing powerups is counterintuitive as staking HIVE helps its value. There's no way I'll power up if 5% goes to the system.
Similarly, taxing the practice of claiming rewards seems ridiculous. What is the reasoning for a proposal of additional taxation rules? How can we know for sure that these rules won't change over time? It's a good topic for an AMA session.
There's no such thing as pure decentralization. You can't have a blockchain like a Hive without someone managing things. So, I see the reason for taxes. You have my support provided management addresses some crucial issues.
I have to agree to a proposal like what you present because there are areas I feel aren't addressed yet. Mr. Acidyo made recent posts regarding unacceptable behavior in Hive. What efforts have been made to address his concerns? Other people have commented on voting abuses that appear to be relegated to the "Whining" section of content.
Since powering up helps the value of hive, a tax on instant down powers makes sense. I see no issues there. As always, thank you very much for the proposal. The engagement will help us grow.
Until the final proposal comes, I will say no to any taxation at this time.
