I realize that. I have family in the Midwest whose parishes share priests, and they are all older. And many of my family in that part of the country would not be able to remember the last time they went to a Eucharistic adoration and benediction. Their churches are often locked during the day, its almost impossible to even make a visit to the Blessed Sacrament (around here its almost impossible to make a visit and find the chapel or church empty during the day).
Perhaps married priests will help their situation, but I suspect it will not make much difference long term. I am not adamantly against the idea. But to deny that it would be a struggle for most parishes is wrong.
You use military chaplains as one example, but that is a bad example. I do not know how much your relatives who are priests make, but I can tell you the salary schedule in our diocese (this was around 10 years ago) for pastors was a little under 30K/year. A salary for a parochial vicar with less than 5 years in the dioceses was around 20K. That was the range of pay for diocesan priests. I do not think it would be much out of the norm. And we need to remember, if we had married priests, it would be completely absurd to expect their family to require two incomes to live. The husband would be away from home for so much of the time, even in the evenings, that the wife would almost certainly be a stay at home mom. Salaries would have to go up by 2 or 3 times at a minimum. In addition to that, if one expects it to solve the problems of the priest shortage, one cannot say that the available rectory space due to a priest shortage would be sufficient to house the families.
