Have you really tried?
Indeed, it's not widespread yet, but there are many bands/websites/record companies out there that do provide lossless audio.
I really like Bandcamp - a lot of indie and alternatives bands and independent record labels on there. You can buy digital only from the website, or buy the physical release, and once you've done so can immediately download the digital versions in a variety of formats - including FLAC, I can't remember whether they do WAV files. I usually download a FLAC copy from the home setup and OGG for phone/portable. I've also bought a few LPs in shops to find a Bandcamp voucher inside to get the digital copy - once again meaning a wide choice of formats for download.
Some record labels still provide CD copies with LPs rather than digital vouchers. I recall buying Shellac's"1000 Hurts" back in 2000 and that's the first LP I bought that also included the CD. I don't think I even hard a turntable at the time! And then the no-vinyl 00s happened and it was a while since I saw that again. Electronic music label Kompakt are amongst several that still do so (or did last time I purchased an LP from one of their artists).
Domino Records LPs include digital vouchers - letting you pick between HQ MP3 or WAV. They're one of the biggest indies.
On a case by case basis, My Bloody Valentine fully embraced all formats with their third album - the LP came with the CD and a digital voucher - download formats included 24bit 96K WAV. Once I got a download voucher and found 192kbps MP3s. I expressed my disappointment to the (very small) indie label, and got a copy in WAV.
But really most LPs I buy nowadays come either with a CD and/or a voucher allowing me to download a lossless copy.
So I'm not sure how come you've never encountered lossless audio out there? I'll admit I'm not well versed in major labels digital releases, but if that's all you ever listen to, then I would question your commitment to music to start with. I'm guessing either that or you haven't tried and yet use the argument as a reason why not to purchase music.
