Well, for starters it's approximately $/£200 more than the current base 15" equipped with 1TB, or the same price as the upgraded stock 15" upped to 1TB.
Then there's the Dell XPS 15, where the lowest 1TB configuration costs £2,149 (i7 and 32GB RAM) or there's an i9 and 32GB model for £2,499, or if you max it out (there is no £2,999 model, it's only £2,899) you get 2TB and i9/32GB.
Razer, as far as I can see, are a bit of a let down and don't offer a 1TB SSD option, but their whole 15" lineup tops out at £3,149 (4K OLED) for that you're getting a computer that will blow this thing out of the water if it's going to be similarly specced to a current 15".
HP's Spectre x360 maxes out at £1,999 and that gets you a 4K/i7-9750H/GTX-1650/16GB/1TB configuration.
So to answer your question, I can pretty much point at the market and show you a $/£2,999 1TB 16" MBP still wouldn't even be particularly great value.
