Firstly, I agree, this is a relatively easy way of putting a limit on the kind of abuse you talk about above, and I'm glad you're 'onside'.

As far as I am concerned having an absence of rules* on steemit doesn't mean more freedom, it just redistributes power and certain types freedom (the two are inseparable) differently.

Having no limits on posts empowers and encourages those who want to put up short form content regularly, but also the type of 'extraction abuse' that's currently going on.

HOWEVER, it makes the rest of us less free because we have to devote time and energy to combatting said abuse - IF we want to maintain our share of the limited reward pool (another 'rule' we're all exposed to).

Your proposition (which I agree with) would INCREASE freedom for most people on steemit - by allowing us more time to create good content, and free us from the tyranny of shit spam posts to a greater extent.

*In fact, there isn't an absence of rules on steemit: if you're posting to get rewards through dual-account collusion, abusers are already effectively 'limited' to the amount they can post by the recharge rate: which is 10 * a day.. it's a still a rule... a 'limit' build into the system... putting a hard limit on this wouldn't be so different.

The whole concept of freedom and rules is something that I need to write about at much more length. Sociology can help a lot here: in short: we depend on structure to be free, an absence of structure may make us less-free.
