"...they may very well suggest meeting in homes."
Not bloody likely!
Back in the day when the Book Study was held in homes...the meeting program consisted of a book, a conductor and reader. I guess you could say the meetings were held more on a manual and simple basis. WT has complicated the conducting of its meetings by going digital and getting the rank and file used to expensive electronic devices and big screen monitors. For meetings to be held in homes would require that the rank and file whose home would be used would have to fork-out some serious cash on electronic equipment compatible to WT standards so that the WT Study and CLAM meetings can be conducted by WT's current delivery. Not to mention that there just 'ain't' that many homes available in any one congregation.
