Why do people who try to convince others to switch to metric focus so much on the conversions?

No idea because I don't know how much a dime, or a nickel is worth, nor what you define as a roll. I can guess a quarter is 25¢. None of those are a decimalized values though, and you're giving nicknames to certain coins because you're still holding to a non decimalized money system, it only makes the system more difficult to you.
A quick Google search let me know that a dime is 10¢, a roll contains 40 coins, a quarter is indeed 25¢, a penny is 1¢ and a nickel is 5¢. And first of all it becomes obvious you need to put large numbers to make the decimalized system appear difficult, I purposefully used small amounts of coins someone might have in their pockets, a total of 23 coins, with no coin having more than their next denomination in value, your example however needed over 130 coins, random nicknames for values and coins grouped in random amounts to try to introduce difficulty.
So the short answer is that if someone pulls out over 130 coins to pay for their meal they will be told to use a machine to count them. But because decimalization actually makes your life easier, a "roll of quarters" is worth 10, a "roll of nickels" is worth 2, and the rest is 77¢, so nope, even with your arbitrary exaggerated amounts and nicknames it's still easy to count it to 14.77. Had I told you five scores of Bob, 3 Baker's dozen Joeys, two threescore Florin, 17 crowns, and 3 ten bob rolls you would still be adding stuff into next week. Math is just easier with decimal currency because we use a decimal numbering system, €5/10 = 0.5€, but £5/10=10s or 120p
