Wait a minute, 6MB/day with 3% of Bitcoin transactions, and Bitcoins blockchain grows at 34 MB/day, that's not 5x the growth of blockchain compared to bitcoin, it's 5.82x, closer to 6x for the same number of transactions.
I was using round numbers everywhere, it isn't exactly 3% nor exactly 6MB. These numbers can't be measured exactly because they vary constantly (especially transaction volume). Nor is your 34 MB number exactly right because that varies too.
You want to tell me that 6x bigger blockchain is not a design flaw
Exactly. It is a design trade off to achieve blockchain analysis resistance, unlinkability, etc.
If you don't think those things are important then you wouldn't accept that the trade off is worth it. Others clearly disagree.
6x is roughly equivalent to Moore's Law over a 5 year time period, which means the cost of Monero in inflation-adjusted computing resources is right about the same as Bitcoin was when it first launched. This is 100% normal in the computer industry. The equipment builders figure out how build faster, bigger, and cheaper and the software builders figure out how build improved functionality. A form of "tick-tock" if you will.
