Your insistence on a hyper-literal translation of "in all your dwellings" is totally illogical. Remember, these things were originally said to people who lived 3,500 years ago. They hadn't invented indoor plumbing yet. In Deuteronomy, we are told:
You shall have a place outside the camp, and you shall go out to it. And you shall have a trowel with your tools, and when you sit down outside, you shall dig a hole with it and turn back and cover up your excrement. Because the Lord your God walks in the midst of your camp, to deliver you and to give up your enemies before you, therefore your camp must be holy, so that he may not see anything indecent among you and turn away from you. (Deu.23:12-14 ESV)
If they were not to go outside their dwellings, were they supposed to hold it in for 24 hours during the Sabbath? Or do you think God didn't quite think this all the way through? This problem can be solved very simply by understanding that "in all your dwellings" is not a commandment to stay inside your house, but is rather to emphasize that the commandment to hold a holy convocation on the Sabbath applies wherever you live. That would make sense, since they had been traveling through the wilderness and were about to enter the Promised Land. God was telling them that the rules didn't change. Also, when they would later move to other countries, they were to keep the Sabbath in the same way as they did in Israel and as they had done in the wilderness.
A convocation is an assembly or gathering of people. In this context, it is what we today would call a meeting, a church service or mass, depending on what denomination is holding the convocation. The command to hold a holy convocation requires that we gather together for a meeting.
It's really quite simple, but if you want to jump through a bunch of mental hoops to try to get the Scriptures to say something other than what they clearly mean and if you want to picture all of Israel suffering through the Sabbath because they're desperate to be allowed to go outside the camp to do their business, then go right ahead. I'll go with the much simpler and more logical explanation that God wants us to gather for corporate worship on the Sabbath, and that He doesn't mind us going to the bathroom that day.
