"Legally binding tax" has nothing to do with accepting payments in Bitcoin. If you account for it right, it's all the same. I do accept payment in Bitcoin for real-life services and it works for me.
All I am hearing from you guys in this thread is "Baaa". You mean you're fine with paying 4k for 11Th/s since "it's all with profits now anyway" or "it's early hence the price"? That's ridiculous.
I sell my s7 at 1200 or so, means this price is only $2800. Works for me!

Can possibly sell the s9's at even higher profit and then just re-buy more A8's. It works both ways on the mining as well as ASIC selling.
