V. The fork is needed because otherwise some people won't be able to use Bitcoin.Bitcoin isn't for everybody. Creating something useful that everyone can use is an exercise in trying to create something that's useful but worthless. Such a thing may exist, in the sense perpetuum mobile may exist. As far as the science of physics goes, they do not.
Should blocks ever become full, older coinbases will be prioritized over newer coinbases, and larger mining fees and transactions prioritized over smaller mining fees and smaller transactions. This means that someone who wishes to pay for very little with Bitcoin will be forced to use something else, so to speak is forced to "give his seat" to someone richer. This is exactly the point and the intent of Bitcoin : to force the poor to yield to the rich, unversally, as a matter of course.
You may not like this, but that is entirely an emotional problem of yours, which you're welcome to resolve any way you can : stop being poor, take a lot of pills, whatever. You may try to solve it by attempting to make it impossible for the rich to construct tools that they will then use to force you to yield to them, but this will necessarily not work : being rich means by definition they have more resources than you, and whatever you devise they can make a counter.
If you are more practically inclined, and having understood, accepted and come to terms with your fundamental human inferiority as it flows from your poverty, some solutions to your predicament of "I wish to buy myself a basket"
have already been discussed :
For the reasons noted and for many other reasons I am pretty much satisfied that Bitcoin is not nor will it ever be a direct means of payment for retail anything. You may end up paying for a month's worth of coffee vouchers at your favourite coffee shop via Bitcoin (so shop scrip built on top of Bitcoin), you may end up settling your accounts monthly at the restaurant in Bitcoin (so store credit built on top of Bitcoin), you will probably cash into whatever local currency from Bitcoin (be it Unified Standard Dubaloos or Universally Simplified Dosidoes or whatever else) but all that is entirely different a story.
Run along now, back to playing in the mud with the other naked kids in your village. Bitcoin's just not for your kind.
