Step 2: Start using the wallet.
Of course, your bitcoins would not be lost providing that you had a backup somewhere and the person that presumably finds your supposed hardware wallet does not crack it before you regain access and shift your coins elsewhere.
Likelihood of being pick-pocketed is rather low. If somebody were to rob you they would just swipe the notes anyway, as well as your phone etc - so that point is moot.
The OP was all about losing money by dropping it and not noticing due to its properties. As a wallet owner myself, I take far greater care of its contents than I would if I were to have them loose in my pocket.
It is not entirely uncommon for people to lose their wallet, either because it falls out of their pocket when they sit down, take it out to pay for something, place it on their lap and forget about it, or a number of other reasons.
