How is the vagueness about the size of a cricket ground also a result of its village origins?

(i) Cricket was originally played on country commons, unfenced land that was public Property.
(ii) The size of the commons varied from one village to another, so there were no designated boundaries or boundary hits.
(iii) When the ball went into the crowd, the crowd, cleared the way for the fieldsman to collect it.
Even after boundaries were written into the ‘laws of cricket’, their distance from the wicket was not specified.
