Some parasites of bees are not welcomed, other are very desired visitors. In the top list of most spectacular animals that you can attract to a backyard garden with its unique mix of metallic emeralds, cyan, golden pinks, indigo and magentas.

Is just a beautiful part of biodiversity.

Healthy bees evolved with parasites and are perfectly able to deal with them and clean themselves. Bees dosed with pesticides not so much.

Wild bees, yes. If you like to keep domesticated bees, I'm not sure your argument holds?

Domestic bees don't visit insect hotels and solitary bees don't share the same parasites as the domestic ones. An apiculturist will need to apply products inside the honeycomb to keep the bees safe in any case.

Burning your insect hotel each year does not matter, the parasites are inside the beehive, not in the insect hotel. Is an advice that only helps the seller of insect hotels. Solitary bees don't live in the nests. They lay eggs, add food, close the door and never return.
