That's an often underappreciated aspect of engineering.
When parts last longer than expected, it is considered something that needs "fixing". It is a signal that the part can be made cheaper, lighter, etc... If SpaceX had gone with heavy, thick tiles, and they did their job because they were overspecced, it is that much less payload capacity.
Even value engineering, which is often criticized when it comes to consumer products is a good thing. Yes, your new dishwasher is not as robust as the one made in the 50s, but it is also 10x cheaper (inflation-adjusted), and it can still wash dishes for maybe 10-15 years without repairs, at which point you may want a new one as technology has improved. Note that I am talking proper engineering, having a single point of failure that prompts a replacement is planned obsolescence and terrible engineering, there should be no single point of failure with good engineering.

It'll still be orders of magnitude cheaper than the nearest competitor for many years. They don't need to fix it before gaining very extensive experience flying it.
