Do you really want to be restricted from having more than seven people in your house at one time?

I don't really think the number of people is the issue here really, it is probably more the frequency and duration.

Many small businesses would rarely have more than a couple of customers inside of them at any one time, but no business would be allowed to be run out of a private home zoned residential.

There is a point (a debatable point) at which a “bible study” would become a church... and churches are not allowed to be built in areas zoned residential.
