I don't think a few percent is going to help, and I'm pretty sure they'd also fill it if blocks were 4 times bigger. It would just take a bit longer.
There is a direct correlation between block time intervals and fees, when the demand for block space is pretty large, every second matters, on the 5th of May, the average block time was 12.01 mins which helped in making things worse.
on a side but related note, Luke Dashjr seems to be pretty upset about what's happening with fees and he is calling for "actions", it will be an interesting scene to watch, I doubt mining pools will signal any change in that regard since they all are enjoying the extra profit.
Let's look at the bright side, Segwit adoption has not increased for nearly a year now, it has been stuck at a 90% level, but it jumped to 95% in no time.
Saying that it gives you the freedom to do with your money what you want won't be enough. The second question will be how much is all that going to cost me? And when you tell that person it could be $10 or $20 regardless of the amount you spend, they'll laugh and walk away. Bitcoin is useful if it does better than what traditional payment systems can offer. Sadly, that is currently not the case.
This debate is déjà vu, to be honest, I will start and finish by saying that almost nobody uses
BTC for daily payments, you may know a person or two, but the percentage of people who use
BTC for daily payments rounded to the nearest whole number is basically 0,
BTC gained most of it's value for being a "store of value" even when fees are dirt cheap it is still expensive and slow to most payments, even if fees were 0 (cash is, most local payments are) how are you going to convince someone to wait for an average of 10 mins to get his coffee?
It almost feels like the whitepaper is being universally misunderstood, P2P e-cash does not necessarily mean (cheap, can buy coffee, fast), or none of that, it simply means P2P,
BTC is not suitable for daily payments because it's too secured for that, it's a part of its strength not weakness, if you want to convince someone to use
BTC you will have better luck (by a few orders of magnitude) if you focus on the value aspect and to show them the chart of Bitcoin, people care more about preserving their wealth and increasing it, than finding an alternative for the grocery store checkout, because honestly, nobody seems to have a problem using their credit card or cash to pay for a cart full of vegetables.
You are going to add to that that "bad money drives out good", we will need to get rid of all the government-printed money first, only then we will be forced to spend dear bitcoins.
Anyway, I am pretty sure this wave is going to be over soon and we will go back to normal the moment this hype is gone just like any other sort of hype/fomo we had in the past, more things will come in the future and clog the network for a few days and then disappear, I don't think we need to worry about it, it will resolve on its own.
