[bitcoin-dev] Why Satoshi's temporary anti-spam measure isn'ttemporary

Gregory, can you please speak to the following points.  I would like a 
better understanding of your positions.

1) Do you believe that Bitcoin's future is as a high-value settlement 

2) Do you believe we need an artificial limit to transaction rate, perhaps 
implemented as a maximum block size limit?  If so, why?

3) Transaction fees will fluctuate with global economic conditions and 
technology.  Those free-market fluctuations should equally affect any 
blockchain.  However, if transaction fees on the Bitcoin network are pushed 
artificially high, such as with an artificial limit to transaction rate only 
applicable to Bitcoin, this will create a condition where some other 
blockchains will have lower fees.  How do you plan to address the bleeding 
of value from Bitcoin to alternative lower-fee blockchains created by the 
artificially-high bitcoin transaction fees when users begin looking for the 
cheapest way to send value?  Modern economic study has shown that liquidity 
moves to the location of least friction.

4) If you believe it's not a problem to allow alternative blockchains to 
leech some of Bitcoin's value, then:
    a) How much value is it acceptable to lose?
    b) How do you think this will affect Bitcoin miners, whose large 
investments in hardware do not transfer to other blockchains?
    c) How do you think this will affect the investors and holders of 
bitcoin in general?

Precisely.  And as "just a payment system" Bitcoin is not an
especially great one: The design requirements for decenteralization
impose considerable costs.  To the extent that the technology in
Bitcoin is useful at all for building "just another payment system"
this technology in in the process of being agressively copied by
parties with deep fiat relationships (including in partnership with
centeral banks).  If the focus for Bitcoin's competative advantage
becomes exclusively "better" payments then it will almost certinatly
fail in the market-place against competing systems which avoid the
Bitcoin currency adoption related obsticles (but also gain none of
Bitcoin's important social/political promise).

Also, critically, if Bitcoin's security properties are manintained and
enhanced then Bitcoin can be used to build secure systems which _also_
accomidate those applications and we can have both. But if Bitcoin's
security properties are not strong then then advanced tools cannot be
built for it.  E.g. atomic swaps make trustless trades with external
systems possible; but they are especially sensitive to long
reorginizations by miners... so they can only be securely used where
those reorgs are infeasable.  So while I agree that we must be willing
to tolerate not catching every conceivable use case; most of the time
all that means is addressing them via a less direct but more focused
solution rather than ignoring them completely.
