Being homeless, traveling in an RV, staying in hotels, all legal reasons to want mail scanning. Google it and you may even find a cheaper service than 1/4 BTC.
Alas, every mail scanning service I could find required prospective customers to already have an address. Unless you have recommendations?
Give us a hint to the illegal activity you are planning.
I fear I'll have to contend with this assumption no matter what I say.
However, I may as well reply regardless: I am planning nothing illegal. That's the point of going to all this trouble. If I was willing to provide a fictitious address to commercial mail scanners, I would simply do
that, instead of offering a quarter-bitcoin to a stranger to rifle through my letters.
