You've got a point. What about a flat rate of about 10c for every transaction above $10? Would that seem more "new world thinking"? what about 1c?
Better but
a) once again you have no idea the value of the tx. Only the sum of the output (which includes the change)
b) the metric that determines cost if the size of tx in kb not the value of the tx.
x cents per kb (rounded up so all tx are considered at least 1 kb) would be more logical. Still I doubt anyone would be willing to pay for it but at least your pricing metric is possible to enforce and matches the critical resources (the size of the tx).
So I guess now we're getting back on track as this is the exact reason I opened this thread in the first place;
My question is: How can I know in advance what amounts and/or addresses does a transaction have in it if the transaction is already signed?
What are my options to understand the incoming signed transaction and evaluate whether I want to push it to the network or not?
