Nobody said the growth would stop, what has been said is: hitting the blocklimit will not cause big trouble because the first thing that would happen would be microtransactions for tiny amounts of money happen somewhere else. So all your doom preaching and urgency is invalid.
Hitting the limit will not render btc unusable - in fact it will clean the chain from spammy microtransactions.
Wouldn't it be bad for Bitcoin, when transactions are happening somewhere(an altcoin?) else?
Spammy microtransactions are those with smaller fees aren't they? So more transactions means higher fee. So, it will lead to private people stopping to use Bitcoin, since they can't afford transactions.
Isn't small fees one of the main arguments for Bitcoin?
Tell me, how wouldn't that lead to higher fees?
