Well... when you have a very high disposable income, no family, no debts, OCD, and a (at times uncontrollable) lust for ###y engineering... well, a $2000 .22LR is somewhat of an after thought.
That being said I did have 2 22LR rifles up there near $2000... and now I have one having recently just sold one, but alas another $3000 .223/.556 quickly followed, as did a $2000 .45ACP carbine immediately after... so perhaps I may have lost my senses a little in the aforementioned exchange.
It could be worse though, I don't gamble or use substances for example... money in the bank does nothing for your obsessions, like you said to each his own.
All that being said, I honestly envy the family man with accountability and more self control. I suspect many on this board can relate to this sentiment.
