When you have a lot of albums it is never a problem. We get bored playing the same record over and over. Say you average listening to two records a day. That is just over 700 records a year. Many of us have 5,000 plus records. A record might get played once every six years. Records that you really like might get played a total of 10 times. With a good system and the best care a record will last indefinitely. The problem is most people do not take the best care of records. I personally do not buy used records. If I was at an estate sale I would consider buying a single large collection. The bigger the collection the less the records were played. Then you sell off the records you don't like.
Under the best conditions a record can probably be played 50 times or more. Time is not the issue. It is the number of plays. Also remember old records were played with either spherical or elliptical styli. Our modern fine line styli produce less record wear.
