The result is that Bitcoin still does the same txs per kb as before. There is no actual improvement in scaling, more like a tradeoff where decentralization and network vulnerability to bloat attacks are tuned to "worse" so that more low-to-zero fee txs can go through.
Such would move the hard cap of somewhere around half a million transactions a day to a higher number. If you do not feel that the ability to process more transactions per unit time is an element of scalability, fine. I find such a position absurd, but so be it. If you insist on clinging to such a definition, than I am more interested increasing potential transactions per unit time than in
your definition of scalability -- at least at this point in time, when we are rapidly approaching that limit.
And despite your repetitive statements stripping the reality, this has nothing to do with whether the transactions are zero- low- or ouch!-fee.
Half a million a day regardless of the fees paid. Period.
It has
everything to do with low or zero fees.
If, say, you go from 0.5mn txs per day to 1mn txs per day and a spammer can add 0.5mn txs per day for peanuts to fill the extra capacity where does that leave you?
You'll go back to square 1 and you'll still be crying "ahhh the blocks are full, we need a new increase, my negligible fee doesn't get me confirmed in 5-10-20 confirmations and I need to pay more and more", etc etc.
But not only will you be crying for the same things, you'll now have to deal with double the bloat, more hardware requirements, higher expenses for running nodes, a more centralized network, etc etc.
Yes. A 'spammer' with sufficient resources can clog the system, no matter how high the maxblocksize is. So what?
That is not the relevant point.
The relevant point is that, at the current maxblocksize, the system supports only a half-million transactions per day (+/-). Period. No more may be processed, even if every such attempted transaction was accompanied by 0.01, 0.1, 1, 10, or more BTC. This is a hard limit currently, and this is an absolute fact. I don't know why you keep trying to deflect the conversation to the less-important 'amount of fees issue'.
In and of itself, the half-million per day limit would be no issue, but only as long as no more than a half-million 'valid' transactions are attempted per day. However, we are currently trending towards saturation. On average, blocks are currently approximately half-full. And in the last year, actual block size has increased 136%. On current trend, we don't have a year to raise this limit before user frustration. We don't have a half-year. If we get a surge in adoption this month (not an unlikely prospect, given the widely-media-discussed doubling in price over the last quarter), we could easily saturate within weeks of today.
When new interested parties arrive, money in hand, but are thwarted by not being able to acquire Bitcoin due to there being no room in any block for their transaction, what do
you think the result will be?
