You could also make people pay MUCH higher prices for perpetual data storage, like 10 times the cost but in return the data will be permanently there, if they so think the data is very useful and important, that way at least it’ll increase the limits to the expansion of the network by 10x too(or maybe not) but either way, if it is going to be PUBLIC data I’m assuming, why don’t people just give it to all centralised websites too, so everyone who find it potentially useful owns the data and has a copy?
if it’s publicly available and useful data, it has no problem going on the current all centralised data sharing sites and staying there forever, and available for anyone to download, and communally maintained if on the safenetwork. And if it’s private and useful data, then it’s the persons responsibility to keep their data safe, aka paying recurring to the network, or keeping the data stored elsewhere, ask friends to maintain it etc etc.
I think you’re also miss calculating just how powerful GBH are. Right now cloud storage is $2 per month per 50GB stored, that’s $2 for 50(GB)*30(DAYS in a month)*24(HOURS in a day) = 36000GBH. So let’s say an important piece of data on mathematics or quantum mechanics is 100MB in a library(so 1/10 of a GB) so with $2 you can store it for 36,000 *10 = 360k hours, which is 15000 days! Which is 41 years!! All for just $2!!! You get your important piece of data stored on the network for 41 years, publically accessible by anyone and you OWN the data fully during these years. So if you really think it’s that important, pay $25 and get it stored for 1000 YEARS on the network! Remember, during this time if ANYONE finds it useful they can pay another $25 and extend it for another 1000 years for other people to discover it!!! It’s not bad having this, and it will make the network not only more sustainable but can expand to much greater limits.
