Many places--Federal land for sure, our Warshington State does (don't move here) have laws requiring timber land to be restocked in X number of years after logging. Not every seedling will survive long enough. Deer, elk, rabid gophers, etc. all prey upon the baby trees. Some will be planted poorly and not survive. Some sites have harsh conditions which will kill a number of trees. It's easier to plant trees closely to assure that stocking level. Also, Weyco has a paper out there showing that seedlings actually grow faster when planted in the usual spacing. As they fill out a little bit, light bounces around in the stand and that makes for the better growth. Ideally, those trees would be precommercially thinned but the first commercial entry, if not a clearcut, can be "challenging". Think of it as a liberal plot.
Oldman47's stand looks good for using a processor to log it IF he had enough acreage to make it pencil out--and a market--and a logger. An easy way to thin it would be to take out every 3rd or 4th row and grab a few trees in between. Limb lock matters not to that kind of equipment. Straight rows are perfect for that.
One caveat about thinning or opening up a stand in conifers is wind protection. A newly thinned area is susceptible to windthrow for a couple of years until the roots compensate and the crowns fill in. There are areas on our coast that are pretty much in a precommercial thin then clearcut rotation because of the winds.
