I think this really is the heart of the issue. You're not following Jesus. You're following Moses and legitimizing it with a reference to Jesus. As the saying goes, "this people draw near to me with their lips, but their heart is far from me".
Jesus expounded on a new understanding of the sabbath where we do not give only one day to God per week, but rather, as fulfillment suggests, we give everyday to God; everyday has now become sabbath. The pharisees missed it. They, like you, argued their myopic view of giving one day to God while using the rest of the week to chase after materialism.
But Jesus said we cannot work for God and money at the same time without cheating on one or the other. He said we will love one and hate the other. He said we should not allow our fears about material provisions like food and clothing stop us from stepping out in faith. He said all the nations of the world chase after these things, but that we should not be like them. He said we should seek his kingdom, first, and that God will provide the things we need.
It's almost certain you will argue against this because your faith is not really in Jesus. Your talk about following his commands and example aren't really about following him, but rather a justification to legitimize your loyalty to ritualistic religion in the form of a once-per-week observation of God's existence while you spend the rest of your time chasing after money. "hey, Jesus kept the sabbath". That's it. That is the extent of your interest in the "commands of Jesus".
He also commanded us to pray, fast, and give charity in secret, but you will probably argue that's not really what he meant. He said we should not swear for any reason, but you will probably argue that if someone asks us to swear on a bible in a court of law or for some other official reason, you'll argue that we need to obey the laws of the land. He said we should not use special titles like father, Mr, and Sir, but you will probably say that we must use these titles to show respect. He said no one can be his disciple unless he forsakes all he has, but you will probably say that's only something to be done in your heart.
Jesus says, "come to me all you who labor, and I will give you sabbath". Working for Jesus is not like working for money. In comparison, service to the kingdom of Heaven is perpetual sabbath. Your argument is contrary to this new principle God revealed to us through Jesus. You want to take us back to the old way where we only give one day a week as part of just another list of ritualistic observances. What Jesus has is so much better.
