Why should the rest of the country subsidize your state's more burdensome tax regime? Removal of the SALT deduction just brings the federal tax code a bit closer to neutrality. If you choose to live in a place with high taxes, that's fine, but don't expect everyone else to help subsidize it.
What you're really going for is that the required service provision level by states should be as low as possible, and if any states wish to exceed that, other states should not need to subsidize it.
Which would perhaps be OK if we had a better democracy, and the decision of a state to provide a very low level of public services truly reflected the desires of its inhabitants. However, all evidence points to the idea that states which actually operate at these lower levels also do their very best to limit the political influence of those would seek higher public service levels.
What you're actually doing is allowing the priviledge of wealth (and power) in some states to percolate up to the federal level to make it harder for other states (and their own) to respond to public desire.
