Well if you are doing laps or enjoying your families you don't need your seat do you? You only need it when you come back and want to sit down. With your family. Meanwhile no other families can sit down. And when you get back you can't because some other family is 'enjoying one another' and some guy is doing laps. If everyone used the chairs when they needed and not when they didn't, it wouldn't be a problem for anyone. See how it works?

There is nothing wrong with enjoying these activities beyond 15 minutes--in fact it's quite normal and routine. When people pay to enjoy their time at the pool, they should not have to worry about the pool police or anyone else claiming their belongings which could be quite valuable.
Of course, there are people who abuse this, but your proposed solution is neither reasonable or practicle. This proposal could easily lead to hundreds of people being improperly inconvenienced and disturbed. It would be a daily nightmare for the customers and the staff--a daily nightmare.
A 40 minute trial is more reasonable and if it turns out that what is gained is not worth the confusion and bad will, then it may be best to work out another plan or revert back to what is current as a perfect solution may not be possible--in other words, a utilitarian decision for all affected parties.
