how does jesus's teaching on 'the sabbath was made for man' relate to this land sabbath?

The passage, plainly, with room to sit with it.

Mark 2:27

“He said to them, "The Sabbath was made for man, not man for the Sabbath."”

This verse comes from a discussion where Jesus's disciples are criticized by the Pharisees for plucking grain on the Sabbath, an act they considered unlawful work. Jesus responds by challenging their rigid interpretation of Sabbath rules.

When might religious or societal rules, intended to benefit people, become burdens instead?
