You just contradicted yourself. First, you agreed with me that most are paying the Tx fee because it is forced on them by the client, than you are suggesting most aren't paying them today? (I'm going to assume you are being reasonable and not arguing against 4 pennies because the drop in BTC value, as a 2-3 penny Tx fee would equally apply to my argument)
Even if clients didn't have a default Tx set (which can be removed in many instances) they do this as a convenience to clients because the users would be pissed at having their transactions taking days to accomplish and promptly add the Tx back themselves.
I have provided some evidence to the table and still have yet to hear your evidence rather than vague allusions.
Evidence of what exactly? The fees today hardly equal a tiny fraction of the block reward, yet you're advocating increasing available space?
Answer this question please which you keep avoiding:
4,000 transactions per block @ 40 pennies each(Full 1MB) vs 40,000 transactions per block @ 4 pennies each(half 20MB) = 20MB block equally secure or Insecure?
Since it's obviously costlier to mine a bigger block, in lots of ways, the expected profit can only be lower if the revenue is the same, and hence the chain is *less* secure.
4,000 transactions per block @ 1.63 usd tx fees each(Full 1MB)
Where are you going to find millions of users willing to pay 1.63 per tx when much cheaper options are available?
Ask anyone with a bit of money in the bank, that's fucking cheap to teleport gold.
