That's not a valid question as it assumes that everyone will be running a pruned full node.
It is a perfectly valid question, because why should one *not* prune? Altruism?
Especially on a chain that adds 1 TB/year...
Why do you insist on spreading the lie of 1TB a year? It is idiotic to assume that raising the block limit to 20MB will insure that all blocks instantly and continuously remain full; most blocks now are only 1/3 full.
I will be happy to carry on this conversation when you can admit that your claim that we will see 1TB a year is simply fear mongering and it unlikely to be realized anytime soon. Until than you credibility has been shot as evidenced by your repeated attempts of spreading FUD despite being corrected through this thread.
Yes, I and other will be happy to continue to host full non-pruned nodes for free. This is in our selfish best interest as we want bitcoin to remain decentralized to succeed.
