if you're selling items for 0.01 btc you should use a third party and not want to clog the blockchain unless you're willing to pay the market determined fee.
by keeping the network fee based you maintain decentralization
the network is decentralized. not free. value your bitcoin and the network they are on. do not promote bitcoin spam on the chain. it will devalue all of your holdings.
Could not have said it better. 0.01 payments can be made in the cheapest way whatever that might be (if there is demand more service providers will pop up like changetip).
One can make 0.01 payments on chain but needs to be prepared to pay fee. If you want to save on fees for your small txs you'll find service providers who help you save up on fees.
All this works itself out with free market mechanisms.
Your car payment can be and will be made on chain and you won't mind to pay the fee for that.
Keeping the block limit means everyone keeps the access to the network but just needs to be prepared to pay fees for the txs. With Gavinfork many people will loose direct access due to bandwidth requirements. (all of africa, a lot of asia, a lot of south america). The Gavinfork effectively prevents access for half the globe. I'd rather pay fee or use 3rd parties for micro txs than loosing half the world for adoption.
