I hope you're mistaken=2C because that would be a serious attack on the
design of bitcoin=2C which obtains privacy and fungibility=2C both
essential properties of any money like good=2C almost exclusively
through avoiding reuse.

[What business would use a money where all their competition can see
their sales and identify their customers=2C where their customers can
track their margins and suppliers? What individuals would use a system
where their inlaws could criticize their spending? Where their
landlord knows they got a raise=2C or where thieves know their net

Though no one here is currently suggesting blocking reuse as a network
rule=2C the reasonable and expected response to what you're suggesting
would be to do so.

If some community wishes to choose not to use Bitcoin=2C great=2C but they<= br> don't get to simply choose to screw up its utility for all the other
users.

You should advise this "=3Bcountry specific bitcoin group"=3B that = they
shouldn't speak for the users of a system which they clearly do not
understand.
