Below are some scriptures that a pastor might use for imploring people to meet more than an hour a week.
"And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart," - Acts 2:46 
"And daily in the temple, and in every house, they ceased not to teach and preach Jesus Christ." - Acts 5:42
"Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching." - Hebrews 10:25
 I agree that scripture does not mandate meeting frequencies, dates and times and I agree that the local body  should agree upon such things. However, the leader of the local body has the authority to establish such things. He has the authority to determine what days and times to meet and he has the authority to rebuke those who do not submit to these meeting days. If that leader feels that the people's response to those meeting times is neither cold nor hot, then he is obligated to rebuke, reprove and exhort them in whatever manner he feels led by God to do so. The people that  have placed themselves under his authority can choose to accept that rebuke and adjust, rebel against the rebuke and murmur about it or rebel against the rebuke and take themselves out from under the authority of that preacher.
"Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you." - Hebrews 13:17
