I agree. The idea of instant coffee? Nope. And the idea of decaffeinated coffee? What is the point?
The excuse "It's just easier to clean up." reminds me of a cookie cutter I found in a stuff-your-mother-used-to-have store. It was big, round, and you could make 10 different shapes of cookies with just one pressing into the dough. My then lover remarked, "Look. The lazy ass bitch mother's idea of a cookie cutter." He nailed it.
Same with coffee. We have the bajillion dollar gleaming Italian copper espresso machines that foam milk into a thick froth in about a second. But when it's just me in the morning, I prefer the Melitta filter routine. I have a carafe that holds six large mugs. Pour boiling water into the plastic Melitta thing containing a number 6 brown paper filter and the appropriate amount of fine ground beans until the carafe is full. Toss grounds and filter into composter. Screw on top of carafe tightly. Pour cups as needed.
Living outside the USA people tend to get confused and stare at someone like me who likes three or four large mugs of coffee (with cream) in the morning. And after many years of trying every coffee bean available, I prefer the stuff from Java or Sumatra.
Later in the day, if I haven't consumed all of the carafe, there's still enough to pour into a tall glass full of ice for a brisk iced coffee. Again, Europeans and Mexicans, Central, South Americans don't understand. After all, they've yet to fully embrace the idea of iced tea.
As for decaffeinated coffee, most wild varieties of coffee growing where it all originated (Africa) tends to be naturally free -- or at least very low in caffeine. It's very easy to buy lnaturally grown coffee beans from Madagascar with low or almost no caffeine , but why bother? Coffee without enough 1,3,7-trimethyl-xanthine is just brown water.
