I understood the point entirely, and you are correct that if inflation continues at this rate for decades, what today are small expenses like lawn care will eventually become the dominant term, eclipsing my mortgage. But I would wager we will have bigger problems should that eventuality come to pass.
Also, don't forget that increased inflation also eventually leads to everyone's compensation increasing. As I am in "everyone"," it will net out. If inflation moderates over the next few quarters/years, the likely impact to me is that I will earn more and so my largest expense (which is fixed!) will be proportionally smaller. But yes, I will pay more for plumbers and the like so I will be impacted by the cycle.
