Some providers are doing that. For example you can rent such bare metal servers from OVH's cheap brand So You Start. But that doesn't make sense if you need something more that one cheapest server. Consider the total cost of buying and hosting such servers compared to the resources they provide.

You are paying more but mainly when the capabilities are better. Example for SSD: Samsung 860 PRO 1TB and "for Data Center" Samsung PM883 1TB both have about 1200 TBW lifespan, both cost about $180.

On the other hand 8-core Xeon 4215 is almost 2 times more expensive than 8-core consumer CPU but it has 3x the memory bandwidth (6 channel controller vs 2 channel), 1TB of RAM per processor vs 128GB, 48 PCIe lanes vs 20 and supports 2-way SMP. That means you can put few times more capacity (cores, memory, in 1U rack enclosure than with consumer hardware. That additional capacity can also share 1 PSU, 1 network card.

I'm not even talking about ECC memory and remote management capabilities available only in server grade hardware.

ECC works on consumer motherboards nowadays, my X570 motherboard works really well with ECC.
