Chug,
There is an inherent risk in everything we do, agreed that flying in a WWII era aeroplane increases the risk but I believe that everyone who OPTS to fly understands that. Definitely not for the 'Snowflake' generation. I'm with Vzlet on this, in that it's tragic but magical and enlightening for many others who wonder why these 'Relics' are still flying.
Nothing is for ever is a nothing but a (Well known) phrase, as has been pointed out, a large proportion of warbirds are virtually new albeit using old technology, however they all have more manhours spent on meticulous maintenance than they ever did operationally.
Ultimately, it's your opinion which you're entitled to, however do take a look at motorcycle accident statistics and you'll see that even with cutting edge technology, people still choose pleasure over (much) higher statistical risks.
